It starts out at 23 degrees timing and got highest #'s at 25 degrees by 2800 rpms. A/f was straight at about 13 I think that is where the line was. He adjust timing up and down and that was the best he could get. He adjusted the a/f up and down and this was the out come. He is telling me there is obviously a problem he tuned a car that had less done on the g5x cam that made 410/389 so what is wrong

but fwiw, seat pressure wasnt the concern, it was coil bind that kept us from shimming any higher, these new springs would have to be way different

It is not listed in your sig, but you have headers right? I am sure the intake will help that cam breathe. MC tuned my car pretty quick and came out with awsome curves on the dyno graph, Nick knows his stuff.
