Whats next?? Any input welcome!

[BDayks]

So I have thinking about the next purchase and upgrades I've done the LMS stg4+ tuner and that's really it other than painted rims, tints, HIDs and subs. Im not looking to make my SHO to its full potential (meth kit, turbo upgrades ect) I just want something little more than stock , here's what I'm thinking...
 
Engine
- Colder t stat 170 or 160
- Pre gap plugs (These two are a must apparently with the tune)
- maybe Proper intake (have a home made one love the induction sound)

Exhaust
- Eventually catted DP's
- Magnaflow Cat back (my buddy said he could get me one new for $900 cash, Good Deal?)

Interior
- couple gauges (ideas??) 
- LED light conversion

Exterior
- Rims

I know these are all common but it would set my SHO apart from the ones around here, 3-4 in my town.
If you have any ideas or comments on what first in your opinion that would be awesome !. Thanks

I'd recommend a 3BAR MAP sensor ($52 at Tasca Parts) ....2 minute install.

It will really improve your performance.  Your tune must be modifed by LMS for this...Free. 
IMHO it's the single best performance mod after the tune, and the biggest bang for the buck

This will be added to my list I just have to find a company that will have it shipped to CND and without major cost! But forgive me of my lack of knowledge but what exactly is a 3BAR MAP? My understanding is its a sensor that monitors boost and a stock 1-2 BAR MAP will only monitor limited boost (11-12psi I think) so does having more BAR allow more boost ??

[crash712us]

No a Bar 3 MAP does not increase your boost, but it allows the ECM to read boost pressures above 14.7psi. Now LMS 4x tune may increase boost pressures. But I don't know what the difference between there 4+ tune and the 4x. I just know the guys that did this upgrade are very pleased with.

[BiGMaC]

As far as 4+ vs 4x (the 3BAR equivalent) LMS tunes, I can offer this comparison:
With the 3BAR and tune adjusted for it (4x) I have seen time slips and Aeroforce gauge pics showing .47 decreases in the quarter mile time, sub 4sec 0-60 and sub 8 sec 1/8. Even with different DAs this is significant.

I second the above. I recently did the 3 bar and 4x tune. I had just done the plugs and Tstat. I saw an improvement of 0.47 secs in the quarter.

4X? is this a meth tune? It's not the same as V8 is it? I just received V8 from LMS, it cant be .4 seconds faster than 4+ can it?

4x is the newest tune, incorporating the 3BAR mod, form LMS for the '10-'12 MKS andSHO.  It is not a meth tune. v8 is the analogous tune for '13 up SHO and MKS. See donk4444's post above.... The new turbo mapping does it.

On at lest two SHOs and one MKS it has made the differences I previously cited..... v8 gave me a 4.3sec 0-60.... When I went with the 3 BAR my 0-60 dropped to solid 3.9sec

Any chance of a video of a 0-60?  Would live to see it!

The tune you are currently running, and the tune that took your 0-60 time from 4.3 to 3.9 is the v8 tune with the 3 BAR map? Was there a v8 version without the 3 BAR? Just trying to get this straight in my feeble little mind.

[BiGMaC]

No problem.... It is confusing at first.. v8 is the base LMS tune for '13 and up SHOs.... It is then modded for physical changes like the 3BAR or downpipes, or catback, etc .... You just tell LMS what to adjust the tune for.

To answer your question.... In my '13 nonPP SHO....Stock tune--> 0-60 5.1sec, v8 (with added DP adjustment) --> 0-60 4.3sec, v8 (with DP and 3BAR adjustment) --> 0-60 3.9 sec.

Welcome Back BigMac.

According to my Aeroforce gauge, I could do 0-60 in 4.2 seconds when I had the 4+ tune.  I thought that was dang quick.  With the 4X, I dropped to 3.94 seconds.  I was on the same road both times.  Ignore the 1/8 and 1/4 numbers - I backed off early due to oncoming traffic.

The 1/8 might be pretty accurate but I think I backed off just before the 1/8 was complete.  In any case, the 4X/3bar is a good upgrade for 2010-2012 SHOs and MKSs.  I understand that they applied some of what they learned from doing the V8 tune for newer SHOs and also a lot of what they learned from doing dyno tunes on a customer's car.

Damn, the numbers you guys are throwing up with this 4X tune has me seriously considering taking a LMS tune for a spin...

[ecoboostsho]

Just loaded my 3 Bar tune today and I have to concur...really nice improvement in the butt dyno. Not sure what they figured out but its a definite upgrade.
