    I think something's still wrong

    After I installed my LT's and ORY I dyno'd at 341 RWHP and 372 RWTQ. Now after installing 243 heads, 220/224 112 LSA Cam, 1:85 Rockers; I dyno'd at 385 RWHP and 383 RWTQ. It seems to me that I should have seen a bigger increase than that. Any Ideas or is that about right?????

    Seems ok to me, in actuality the just LT WHP seems low. I have stock manifolds and dyno 330 to 360 on my 02.

    Was the second tune on a mustang dyno I heard they dyno lower #'s, still I wonder what kind of difference porting the heads would have made?

    Find someone who does dyno tuning, and runs Dynojet. I would bet you'll see higher numbers, definately over the hp tuners...

    The second tune that was done (Feb 09) was on a dynojet after being tuned with the hp tuner software to run with the new cam.....The first tune I had done (Sep 08) was after I installed the LT's and ORY. It was done on a mustang dyno and with only a modified predator tune.

    Does seem low. 243 heads, as far as I have heard, outflow the 241s. With the cam, LTs, and the heads you should be getting closer to, if not OVER 400rwhp. My GTO is running 343 rwhp and 328lbtq with stock 241 heads, unknown cam, K&N FIPK and SLP LMI exhaust. What other mods do you have(Intake manifold, CAI, exhaust)?

    Aside from the heads and cam...1:85 rockers, P/P LS6 oil pump, CAI, smooth bellow. still have the stock LS6 intake and P/P Throttle Body. After talking with some other people the cam might not be degreed properly....
