2011 ctsv

working on a new CTSV we put heads and cam upper lower pulley. headers and complete exhaust, we done probably 8 or more of this cars making from 540HP to 700HP to the wheels, this is our first 2011, the problem we are having is when you hit it hard it feels like it opens and closes the throtle, or it has some type off tracrtion control look every where in the tune PCM and TCM and compare previous tunes and can't find anything out of the place, the car has 100 mile any help would be great and yes we try all T?C modes:doh2:

thanks

The 2011 calibration is almost identical to the 2010. It is probably just some limit table you need to modify, and make sure your boost isnt being shut down via the computer/boost controller.

thanks for the heads up on the new OPS to torque tables are difrent so by increasing them it would make it do, just finish the car tonite 680HP 664TRQ sweet:hihi:
