2001 Z28 H/C swap results...
Okay, just got my tune dialed in after having my mods installed. Went with the Patriot LS6 Style heads (59cc), comp roller lifters, comp cam (XR-275HR-12) 222/224 with .56x/.56x lift @.050 (its my DD), 255 LPH fuel pump, Headers, OR Y-pipe, HP Tuners, Dyno tune.
Dyno numbers were between 385 and 395 RWHP and around 375 RWTQ. The dyno was reading 95* with 20% humidity. I was hoping for some better numbers. I know the dyno is a tuning tool, but for all the $$$ I just spent, I wanted to see 400+ RWHP. Before the mods, the mechanic was predicting close to 430 RWHP judging by the flow numbers associated with the heads.
A/F ratio is steady and around 12.8, do you think I am leaving horsepower somewhere due to the tune? Any opinions/suggestions appreciated.

every dyno is different. u got ported throttle body? if not get a ported t/b and pulley, probably better Y, maybe add a flowmaster merge on it, also catback? is it just flowmaster muffler on stock piping? if so get a good catback, and u'll definatly hit ur 400+ mark. other then that ur right on par with everyone else. solid numbers. pretty much the setup i'm gonna go with.

Its the cat-back system. Started with that long time ago. About to add FAST 92/92 combo sometime soon. We'll see how that affects it. Still very quick street-car that rips up top. I like it...
