A couple issues with an out of the box tune. Wondering if other experienced?

That is quite a bit a boost if that is a sustained reading...That's even a little high for a boost spike. ANd your 2-3 gear shift will give the largest boost spikes so I'm not surprised to hear that is where you are seeing the large boost reading.

Might want to look at your fuel pressure when that is happening..When your fuel rail pressure drops that can also be dangerous also.
If it's dropping below 1000 psi might want to take it easy.

Just didn't know if seeing 20 psi on an otherwise pretty stock car with a 3 bar map was something that would be considered normal. The car pulls hard, but it doesn't seem like it is without problems. Trying to get a hold of a laptop that can run the live link software. Can't seem to get it working to on my windows 10 laptop to go datalog some pulls properly because it keeps crashing... And the windows 7 laptop that runs and connects properly has to be plugged in 100% of the time to run. Go figure!

Just got another tune from them with lower boost profiles. I guess it's my turn to start figuring out my datalogging problem to get this 100% sorted out.

Feel free to post data logs when you get them and I could take a look for you as well as others we could help you make sense of what you are seeing

Welcome Jordan! What year is your SHO? Is it a 15 SHO ? Current Mileage?
Due setup an intro @ your earliest convenience.  TIA.  Z

I'll be sure to post some of my datalogs once I get some going. I am going through torrie at Unleashed so I know he will steer me in the right direction once we get going.

And the car is a 13 SHO with 100k miles on it as of yesterday!

What tires, how much tread, and how much pressure are you running?  Shifts can be softened up a bit, that might be all that's needed.  Also, an additional quart of trans fluid above the full mark is recommended by Livernois due to possible cavitation issues with hard launches/cornering.

Is maintenance up to date?

[Jordan]

The tires are Pirelli P Zero Nero All Seasons 255/45/19's with 8/32 minimum on each tire running about 34 psi on each one. I will look into the extra quart of trans fluid. Would have never thought of that, but it makes complete sense. As far as I know the maintenance is up to date on the car, but it could probably use a second look. I bought the car ~3 months ago from a dealership where it was a 1 owner highway miled car. (91k in a few years has to be mostly highway I would assume) Is there any specific major components I should check out? I plan on doing a PTU fluid change here soon as I have heard that could be a failure point down the road.

[SHOdded]

The basics:  all fluids either flushed or exchanged, including trans, ptu, rdu, coolant and brake.

Also check turbo piping for loose clamps, cracked piping in the clamp area, and pooling oil in the pipes.  A light misting is normal. 

Take pipe which goes from intercooler to throttle body, and disconnect at the intercooler.  Check crud buildup with the engine oil dipstick.  Less than say a 1/4 " is ok.  There is a HOWTO on checking and cleaning the intercooler.

Secure the turbo piping at the wastegate solenoid atop the intake manifold.  These are the small diameter pipes coming off the solenoid.

All I got ... For now

Alright awesome. I will have to check up on everything. Getting cold out here so I will check on everything probably around thanksgiving when I have access to a garage to be good about it.

[SHOdded]

Good luck, hope everything turns up roses (except ptu fluid, ew).

Are you sure its wheel hop? I know that some of the tuners disable the torque management on shifts, combined with the added spark, along with the dialed up shift pressure will cause the transmission stutter.. feels like wheel hop until the trans finally locks into gear. Usually dropping the shift pressure, spark tuning, and/or torque management will fix this.

20psi is not atypical for several sct based tuning companies on boost spikes. A couple of them do not do anything to control boost spikes, so you might just be seeing the spike numbers..

IF you are concerned contact your tuner... post logs here if you want third party opinions.. AJPTurbo is one of the best resources for getting solid feedback on logs if he has the time.

I can tell you from first hand experience that different strategies behave differently when tuned.

Good Luck!

You dont need a laptop to actively save a datalog. I recommend reading through this thread on how to do it with just the sctx4 hand held. And then transferring the datalog to your computer afterwards. Generally better resolution as well.

Ah, well I am using the bullydog BDX which is SCT, but when I was able to hook it up to the laptop there was no dataogs on the device. I am pretty new to this whole tuning thing, if the BDX can do the same thing that would be awesome I would need to look into it I suppose.
