What should a '14 MKS with a 93p and a 3bar run?

I would say anywheres from 3.9x with IDEAL conditions and race prepped (weight redux, 1/4 tank fuel or less, hotter tune, etc) to 4.5x in full street guise.

Depends greatly on your mods and launch style.   I am running JUST a 3-bar, pump-92 and .28 gapped plugs on a AJPTurbo tune and I am just now getting 4.5x-4.6x on non-prepped full street on a 2k launch. (but it ruins my 1/4 mile to launch @ 2k) 

If i did the downpipes and catback I *know* i'd gain another 150 milliseconds and maybe a hair more or so on pump gas.
If i went further and did a e20/e30 tune I'd gain another 150-200 milliseconds on top of that depending on atmosphereic conditions, elevation and tires.

Others here run e20/e30 + METH spray with downpipes+catback and can pull anywhere from 3.8x-4.1x with a hard 2k launch.

the mods 100% make the car beyond the initial gains from the tune.   and the tune also plays a big role. 

Depending on your lifestyle you may want a safer tune, that will make your 0-60 slower, but keep you from fuel shortages, bad knock and super hard shifts that will reduce the life of your PTU and connected bits.

if your more aggressive you can run some vendors tunes that pretty much go balls out 24x7.  but you will eventually cause wear and damage.

the warranty can also have a great impact on your cars speed.  I have a 4 year 100k all included warranty on my 50k mile SHO.  so i CANT install downpipes and catbacks because the dealership here is supper sphincter tight and would invalidate any claims due to being modded.  so i run only the 3bar i can swap on the side of the road and the tune. thus I get to run slower.

Before you pull the plastic i'd find a shop that will work on your car despite being modded if possible to keep you warranty intact.  if the shops wont make a gentleman's agreement on that you might be limited in mods until it runs out... or you risk it.

OK, just checking. After a few datalogs with the x4 they all consistently calculated to around 4.7 to 5.1 which doesn't seem accurate to me.

How accurate is the x4 when you use speed + mph to calculate 0 to 60?

The tune feels aggressive but the shifts are never harsh. At WOT they're even smoother. Now I did have some knock at first but I blame it on winter gas and a combination of my oil shearing down. I've used mobil one for over 10 years with no issues, but I've moved to royal purple plus they make it right down the road. I'll say mobil can't handle the turbos past 5k.

PTU oil looks great after multiple launches with royal. It was still purple at 5k.
Plugs are at. 28. Pipes, Meth, and many upgrades are on the way. I'm willing to sell my boat to make this the worlds fastest mks lol.

I'll be posting my progress!

What are your mods?

My SHO when I do not launch at 2k is exactly where you are.  Consistent 4.7-4.8 and higher as the intake manifold gets hotter.

Post a log and include your mods in your sig and others can review your setup and give pointers

For *my car* I found the SCT logs to be very accurate for determining 0-60 and 0-100 and estimate my 1/4 mile

Excessive wheel hop will throw of the SCT times though

I see... I'll be doing a log tomorrow morning for Torrie, I'll post it up then. Hopefully this is the first conservative revision.

I feel using logs is most accurate... with the calculator I got 3.8 0-60 with logs 4.4 using a log from my 12.4 run and my 12.4 timeslips to calc the 3.8

I agree with the 3.9XX being attainable in ideal conditions. I can hit that with my 2010 MKS .  3.94 to be exact.  I don't do anything special or any weight reduction beyond not testing right after I fill the car up. LOL

Are you getting any wheel slippage? I would hit 5.2 stock - perhaps you are getting wheel spin?  How fresh is the rubber?

I just a 3 bar 4X PLUS (with soft shift 1-2) 93 octane tune.....

3.9x is crazy fast for only a 3bar!

Michelin pilot sport a/s 3+ less than 5000 miles

I get a little chirp at launch, I do see that I'm losing a few tenths at 9.38mph where it drops down almost to 8.5mph.
The fuel pump percentage also drops dramatically.

I can evaluate these numbers and see where the losses are but maybe someone can tell me why?

This also happens again at 43mph.

I'll attach a log for review, I sent it in to Torrie and was told it wouldn't be revised based on the knock rates. You'll have to zoom out quite a bit to see the individual launches.

Yup, every run the knock sensor is pulling timing due to knock conditions.... are you running the correct octane gas? Could be a really bad tank of gas as well....

Agree. There are 2 of us who had/have  2010 MKS' running those numbers with the same 3 bar tune (Brucelinc and me).   Bruce has a Conti now.  Bruce's MKS was actually a tad faster than mine......

Couple weird things I see in the log....You are commanding almost 15 psi but yet you are barely getting that even on your boost spikes...and your boost is tapering very badly down to less than 10 psi I even saw about 9.2 psi at redline. That's even more weird because your wastegate duty cycle is pegged at 100% in places....You should have no problem exceeding 20 psi with that kind of duty cycle.

I don't think there is anything wrong but I suspect it's because how the wastegate settings are in your tune but there is no way for me to verify that.

I also think you 0-60 times are hurting because you never really reach very high boost and it tapers....When spooling up you normally see the ECU overshoot the boost targets which isn't bad because it's gets these big pigs moving but when your boost tapers to 9 psi in 1st and 2nd gear it's not surprising to me that you are satisfied with yoru 0-60

What is the elevation where you live?

Boost leak possibly? That's what it sounds like to me.

My elevation is 8,749 feet in Houston. And I may have a boost leak or a failing turbo, I followed one of the hot pipes and I have very little burnt oil on the passenger side turbo.

I've ran 93 from shell, chevron and Exxon all with the same results.

Should I try some new hot pipes? Also my cats are reaching 1700F, which to me sounds like they are melting. Might need catless dp's as well?

Or is it just too much knock pulling timing? My sensor is isolated and wrapped in a rubber hose. I replaced the plugs 8k miles ago, maybe I need to go to a colder plug to deal with the houston humidity and heat.

1700 is a little warm for my taste and cat protection mode should step in if it has not been disabled.

8700 feet in Houston, TX?   Don't you mean between 87 and 100 feet?

Yes, you're right I googled Texas elevation instead of sea level. Brain fart 🤗

I thought that seemed awful high... lol

I think you are over thinking things....your knock retard looked normal

Like i said before you arent really running that much boost....but yet your wastegate duty is really high.....you should try a stock tune and compare boost and wastegate duty....i dont think you have a boost leak...i see some of unleashed tunes that run really high duty cycles

Yeah, I tend to over think everything. Which leads me to buying more performance parts, and going faster makes me think like this 😱😁😏.

But the knock does look OK, I could've sworn I've hit 14.6psi when I first tuned it. I'll see if I can do a stock run tonight.

And are you hinting I should try one of your tunes AJP? 🤔
Cause' I'll do it!

I think you were hitting somewhere around 14 psi but just at the shift spikes then it tapers badly

You were less than 10 psi at redline and that should not happen at 90% wastegate duty UNLESS you are in the mountains and high elevation, which you are not ....your elevation is 100 feet correct?..

Or like f8tl said and you have a boost leak ....you could but i have seen unleashed tunes with high wastegate duty and lower boost

If you run the same logs stock you can rule that out

Stock log attached.

I may be counting wrong but it looks like a 6 second stock 0 to 60? Somethings not right.

The waste gate and boost pressures seem to be tune specific. Stock they are linear and tuned it does that weird thing where the gate is almost 100% yet boost tapers. It seems to taper after 4000rpm, or right before a shift. Must be how the tune is set up. No indications of a boost leak.

I think you should just have ajp do your tune, you won't regret it...

I might just to see what it's like. Why did you switch?

AJP has been a little more helpful than unleashed. All I get from them is I have knock and can't revise. No explanation on times or values.
Now I'm not saying he's a bad tuner with poor customer service, I always received quick responses, just not very detailed.

I'll assume it's because I'm just a peasant trying to leech info.

Same reason, not much explanation. If you have questions he can help answer them, and he knows what he is doing... my car hauls ass also..with no mods other than tune and drop in filter

I ran a 12.4 on unleashed e20 tune in 40* weather. Iats didn't go past 125*
Ran a 12.5 with ajp e20 tune in 70* weather... iat2 was up in 160's, so I'm pretty sure ajp's tune will be better in similar conditions

I am headed back up to PIR in Oregon this Friday .. now that I *know* that hard launches rob me of almost 500ms off my 0-100 I have high hopes to break into the 12's finally on pump-92. 

I will install the 170tstat and adjusted fan settings probably tomorrow as well. 

Crossing fingers,. Really want that 12 second time slip...

Well, it's always hot and humid in Houston so I'll assume both tuners would yield similar results when it's 95 outside. I'll invest my money into catless pipes before a new tune. My main issue is the small amount of knock that's pulling my timing. I've got kr below +2 as of yesterday, which I contribute to the fuel octane being barely adequate during WOT. And I'm willing to bet the reduced egt's and higher flow will almost eliminate my knock. I know it's dumping some fuel to keep the heat down. All that extra fuel has to be going right to the cats.

I get the knock down, and Torrie will make my tune more aggressive 😁

Catless down pipes and custom direct port methanol system are on the way.
