when doing a l67 swap into a car other than one with the l67 option, such as a cavalier is there a security or feul enable to code into the pcm? im running times in the 15.0-15.1 stock with the l67.The grand prixs run this stock and are 600lbs heavyer. So why an i slow? i have intense standard pcm for a 99 gtp. Also im using the 4t65e. my best 1/4 is 14.3@101mph. i have a scan with a 3.4 pully, ported tb, 104's, standard pcm, open exhaust 2.5" and cold air.
