The problem just very well may be WHO did your heads...... I bet you'd run better with stock heads than the TSP pieces. It wouldn't be the first time I've heard of someone's stuff running out better with stock untouched heads than the TSP stuff. Might want to throw a set of stockers on and amaze yourself.

well that sucks with the heads, they look like a decent job, i would be really pissed though if the stockers ran better, but anyhow my stockers needed a valve job, hence why i bought the PRC's. the TM is turned off and i dont know what timing is as synergy tuned it just the other day. now dont get me wrong, it does run strong, i just figured it would run harder thats all. was also hoping for closer to 400hp on the dyno, now i do know it is just a number and doesnt mean ****, but was hoping to see bigger numbers, and kinda thought the peak hp would be a little higher in the rpm than 5800.

well i can only speak from what i have seen by running 4:56's my mileage hasnt been hurt in the least, but then i do a lot of stop and go kind of driving. it hardly ever see's the highway. at around 60 mph my tach is at 2100 rpm
