before i had the headers and the dynotune the car was running a 12.4@115 now after the headers and the dynotune the car will only run a 12.7@112. i have been told that the car should be running alot quicker than this. i made 390rwhp and 351rwtq with a baby cam 212/218 .522 .529 comp cam and stage 2 ls6 heads, bbk throttle body, slp lid, and 3.73 gears. this was through the stock converter on an a4 tranny. the car was tuned with hp tuners. what could be the problem?

The stock converter is killing your times. Was the temp out side hoter on the day you ran a slower time?
