LT's ORY, & cat-back results
what else is done to the car, do you have the stock cat back? lid? 317 sounds about right and yes you would pick up a little more power with additional timing. your knock sensors must be pulling some timing out. who dynoed it?
Dynocom DC-1800XSE Eddy Dyno
i have 3in td's with an xpipe dumped through 40 series flowmasters,slp lid,ported mass air and throttle body, and predator prog. the car was dyno'd by jason at lsx tuning in greencove. he mentioned that locking the converter would help but he didnt recomend it and also said it was lean like around 14.4
