Looks like the mods are helping. If you lean that thing out a little you would pick up another 10hp at least. You can see my numbers in my signature and I only have a Vararram CAI and a tune. Try to get that Air/Fuel mixture to the 13.25 mark. Its not that dangerous and you will make more HP's. My numbers we also done on a Dyno Jet.

The fuel air ratio needs to be leaned out a bit. If you look at the A/F ratio @ 5000rpm it is +/-12.0:1. Get it dyno tuned and get it back to 13:1 you will be looking at a real nice gain. Your A/F should follow along the dotted line.

last week i dyno'd 373 rwhp without headers...all i've done is x-pipe .b & b prt's with open airbox, k&n, airbridge , & coupler...the tuner did 13 pulls before we settled on it..12.4 on A/F, was at 11.9 before tune.... and mine is an 01....tuner said he could get more..but made major adjustments in mid range with timing and A/F etc....gained almost 25 hp in the 4000-5000rpm range..good luck and hope you reach the gains your looking for
