You can't advance the timing with the ECU, it does it automatically. As for cams, what kind do you have? There's really nothing good out there besides the JWT cam which are just now coming out? As for what to do now, it depends if you want to go all motor, nitrous, turbo, etc.
i have vitek wires 8mm, iridium plugs, an ACT stage 1 clutch, but no ECU, no cams yet, and what's the throttle body mod and what does that do? how much does headwork cost and where? piston work, how much does that cost? if these are fairly cheap mods as in not over $1000, I'm willing to do it! anyway, help me out here, I'm looking for all motor. nos is not permanent power if you know what i mean.
It might not be long before that changes... We've been speaking with a company about making high quality reasonable priced pistons for the GA....as soon as we have some addition info I'll pass it a long..
