ARH long tubes and LS6 manifold installed I just had my new set of American Racing Headers, catted y-pipe, LS6 manifold and Spohn solid mounts installed along with MSD wires and NKG plugs. Dyno reading before install was 331 h.p. and 336 tq. After install was 353 h.p. and 362 tq. the tuner said he could get about 5 more h.p. but it would be right on the line of being too lean. Does this sound about right for these bolt-ons? The sound is great and at WOT is super great. I can feel the difference from 4000 rpm's to redline. The solid motor mounts make my rear view mirror vibrate a little but that's O.K. I love the solid feel of the transmission and clutch. Can't wait to put on the M.T.'s and go to the track.
That sounds great! If you see in my signature I am getting long tubes, and LS6 intake manifold and a dyno tune next. Now I know what to look forward to, about 22 - maybe 25 more HP at the wheels!
Sounds great! I think a Lid and Ported Throttle body will get you into the 360's at the wheels unless you already have those but I don't see them listed.

yea I had a lid but then I got an FIPK filter and cut a hole in the supplied radiater support under the filter and got the free ram air mod. The tuner said that was the best set-up he has seen. I thought it was just as good as a lid or even better because you can here the T.B. sucking in the air and I think it looks better than just a lid.
I think those numbers sound pretty awesome, considering your pretty much full-bolt ons. Also that 9" takes away more HP then your regular 10 bolt. So yeah I would say those are solid numbers. Good job
