Got a cts v 2009 that jerks at WOT any of you guys experienced that before?
Car has a nick williams 102mm tb, ported snout , ported heads, 227/235 cam, fogger for nitrous, huge hx, icebox, and 5 inch intake and full kooks exhaust iirc.
Car starts jerking only when it catches traction only. Also car is on id1000s
Maybe fouled plugs? Afr is at 11.3 when its spinning, but wideband fucked up before it caught traction so im not sure on afr. Timing is at 13 degrees.
Any thoughts guys? Ill post the file soon.
edit: posted the file
might think its the TCC lockup ?
