Hi guys ive got a top swapped 2002 Monte Carlo SS. Mods are as follows:
L67,L36, 3.4pulley, VS Cam, Wizaired Intake, DHP Wideband Tuned, Drilled 180* Tstat, SSAC Headers, GMPP Cat-Back, HD Diff upgrade

Staring at the end of last summer from a 2nd gear pull through 3rd gear so about 40mph till 120mph i started getting up to 9* of knock, it never used to do that before. The car was tuned in summer 2010 by dave petinelli out here in upstate ny and used a wideband on it and everything. Car ran great and barely would ever knock maybe 1 or 2* once and a while. fast forward to now it knocks 2nd through 3rd gear. i dont under stand so i did 2 logs today, one in DHP and one in UVScanner. i keep the car tip top new o2 sensor, plugs etc. here are the logs any help is much appreciated!!!
