I am working with a 2011 Silverado 6.0 A6 with a TVS1900. The truck is fairly stock with the exception of the blower (3.0") upper pulley, shorty headers, cat-back and a CAI. I have tuned the MAF so that it is very well setup and feel the tune is pretty well setup. The issue that I am having is a throttle surge or lurch when you are slowly moving the accelerator pedal down. If you open my log using the config posted you will see it happen in frame 17.70. The truck lurches momentarily and then settles back in as it should. When it lurches the TPS position jumps from around 40% to around 60% and it spikes the boost to around 7psi.
This is definitely a torque request setup issue. I have tried running the truck with a variety of TM settings and this issues does not appear to be changing. In the log file you will notice that the pedal axle torque request jumps up and appears to be the input that the pcm is seeing to push the throttle blade open. I don't know what table/s affect this and was hoping someone could help shed light on the subject. Thanks in advance! Carl T.
