would you notice a difference on an all stock car that just has an exhaust.. if so, what would you most likely see?

 

check out madz28.com


my first program from him with only LT headers on my car and i really noticed a difrence.

 

Its not uncommon at all for us to pick up 2 tenths /2 mph in the quarter

Best gain i've seen so far on a all stock car has been 22rwhp and 28rwtq

 

i picked up 6hp/12tq on a hot day on the dyno a few months back. it definately felt like more than the numbers said, but i really liked the overall drivability of my car afterwards. it really is a night and day difference. but im going to send it back to bring up my a/f from 12.5 to 13.1 so there is a little more left in the tune. i didnt get into 12's, but i run 13.0x's consistently in crappy weather now. im just waitng for some better weather to get into 12's with just bolt ons.
