Ok, I have an 04 GT with full exhuast, edelbrock victor Jr, custom sheet metal intake, edlebrock rails, 255 pump with a KB BAP, 90mm Maf, Vortech V1 S-trim with 3.33 pulley and fron mount 3 core intercooler. My tuner and I cannot figure out why in the hell it wont make more than 360 rwhp on 10lbs. Any Ideas?? thanks

what a/f ratio? any dyno graphs you can post?

whats the compression ratio of the motor? have you done a compression test lately to make sure you dont have any dead holes?

fuel injectors? and define "custom intake". usually that means some redneck home-made piece of crap.

The air fuel is at 11.5 WOT. The intake is custome built to fit the 4150 style flange of the edelbrock victor jr. Its on 42lb injectors. The custom intake is a professionally built sheet metal upper by MMR.

whats your timing set at? what do your IAT look like? There are alot of factors that go into it. Could just be your tuner.

tedster429

I think there is 17 degrees of timing in it

thats pretty conservative

tedster429

Really? I actually thought that was pretty aggressive. hmmmm.

my buddy ran 25* total timing on a 10:1 motor, no intercooler and 91 octane fuel. im running 27* total timing on my motor at 11psi, 9:1 compression with intercooler. no detonation at all

Im going to call another tuner and see what they say.
