    Thats awsome..What was the car? also this might be a stupid question, but i really didnt understand this, If you get bigger fuel injecters, and fuel lines, with the fuul pump, will this all hurt your miles per gallaon driving city?

    Sounds about right, Sarge.

    You getting any ping at low(ish) RPMs in a high gear with moderate/heavy throttle? I can't remember if you have an auto or M6...

    Built 408 Stroker in a 04 GTO. MPG has never been a consideration for me....but yes as you power mod MPG will suffer...but I get amazingly good MPG 20+ on the highway cruising and 15mpg around town....all in the tuning....

    I didnt think you'd have any ping, not with that AF.

    You should be fine. Just struck me ass odd you'd ask.

    Who does your tuning? I'm going to need to flatbed the redheaded bish over in a month or so. There's not a single GM tuner in my area.

    Vortech and long tube headers are on the way

    I live in the Detroit area and see all the prototypes Holden sends over as GM figures out to badge them. That said Sarge has not only put a motor in that smokes any other N/A goat, but has added a look that Pontiac should have thought about before launching the name.

    I p/ued an 04 and the first mod was a dual out both sides... No performance vehicle has a single exhaust.

    That's for the gen-x chumps who don't know what n/a stands for as their momies still change their diapers...

    Raw power is a big cam & intake while you're standing there and can count the rpm's...

    No juice, no propellers or inpeller's adding power.

    The '04 GTO did have true duals from the factory.

    Big cams are overrated. Sure they sound good at the cruise in, but they suck for normal cruising. Still plenty of power in "baby" cams if done right. Been there, done that.
