THROTTLE BODY IS CLOSING E39A Buick Verano T(urbo)

[Boost]

I have come to the point of finding the limitation of this mindbogglingly high performance 4 cylinder engine that GM made. (2.0 liter LHU Ecotec in my 2013 Buick Verano with 6T50 automatic transmission)

Before I acquired this car, I went hundreds of miles from dealer to dealer pretending to test drive them and plugging in EFILive to see if there was support. I pulled their files and sent them to EFILive.

Finally there was E39A support released and the trans. being an T76 similar to the Cruze which is very much supported, it was only a matter of time (in my mind) until my new special car I've worked hard for for 5 years would be fully tune-able by my favorite (and only) calibration software.

As I lived with the car and pushed it to it's limits, I've accomplished performance that has impressed and shocked many, and have always given due credit to EFILive. But now I have hit a hard limit and there is nothing I can do about it.

I have installed a full intake and exhaust and without EFILive the car would not even run or idle. I have used a COMPLETELY different Regal MAF, and had to modify the ECM wiring. The car runs great and very, very hard, but as I am producing 31 psi boost on the stock turbo (I know) and 361 lb-ft torque on the stock trans. (which is rated at 258 - and acts like it), I need MORE control.

The throttle body is shutting to 40% during full acceleration due to torque reduction request from the TCM and bringing the tire shredding, turbo screaming party to a screeching halt.

This all really makes me sick, so I am posting my logs and findings in hopes that someone can chime in and eventually help will arrive so I can beat rival cars that this engine laughs at in a Cobalt SS (LNF, tuned by competing software).
