I have posted about my issue and build in the other Unnaturally Aspirated section before, well a portion anyways. But, I think its come to advice at this point.
Bone stock, Jeep ran 14.2, felt and performed as expected for location and age.
Had a shop that came highly recommended for my area to install a low boost twin turbo application. Work looks professional and many others from track to car shows said they like the workmanship.
BUT, that's where the good stuff stops, 6 months of LIMP mode issues finally resolved as it was their tune. At the track and it finally ran a 14.9 with horrible shift lag.
Installed a Karma TCM which improved the shifts, but now it runs a 15.3 at best.
Everything feels quick, but something is definitely off. Listening to the engine, no ticks, no dings, not even a belt squeak. But anything more than that and I am at a loss. I purchased an MPVI2 so that I can scan log in the software/hardware they used to tune the vehicle. But I am not getting much out of my tuner in the way of help to figure out the issue.
I'd like to just take it to somebody to have them look it over, go through all the tuning, and see if anything stands out as the issue. But every time, some one gives me info and I send to my original tuner, they have a reason for that issue. Such as the LTFT being at -32 all the time. They say it is because they turned off the O2 sensor for LTFT.
Anyone have any recommendations, suggestions, or trains of thought that could get this brick moving the way it should? I have very few shops with tuning capabilities down my way. And with the vehicle being a 4 wheel on demand, it really needs an AWD dyno.
If anyone wants to see the tune or scan logs, let me know, I have them, but didn't want to post clutter. And I am not looking for a free tune, but definitely willing to pay if a shop thinks they can fix it or solve the issue.
