So you P&P'd your heads and got a chip and you knock .8 seconds off of the average stock times....Why would you P&P your heads and not open up the intake or exhaust whatsoever? That is a s$^#load of money to be spending if you're just going to stop there. P&P gave you 20whp AND 20 ft.lbs and the chip gave you 15whp and 15 ft./lbs huh?...do you have any dynos to prove this VERY skeptical claim or time slips from the track? I know if I got that time I would MOST DEFINITELY get a slip, at the least.
