Meth Injection on N/A

Well how can you advance your timing if you have no ability to tune it? Honest question.

IMO you wont see 20-30whp gains from just an octane increase/meth kit. Thats pretty unreasonable. But if you are eventually going to go turbo, then put it on and let us know what happens.

Like you said, almost no one does it, theres a reason for that. Cant really ask a question if you already know the answer :P

I can tune via piggyback.. that's one of the things I have figured it out. end-user tuning is not available in the M3 world so no one can flash and even then its not full access flashing no one has been able to do an ECU based turbo system on teh e46 m3. So I did some research, hooked up with a piggyback builder in australia, worked out the specs and now I have real-time tuning with 100% fuel control via injector drivers and timing done via altering crank position signal. Just no control over vanos. But the big thing in the M3 world now is wiring up standalones as piggybacks and retaining full emissions compliance... amazing stuff. I cant figure it out but hopefully I wont have to worry about vanos tuning. I am hoping the stock vanos map might be a good one for a turbo setup?

I just thought that no one had done it in the M3 world, but maybe it would be more common in larger Import scene which is why I asked here. But we will see how it goes. I figured with the 11.5:1 compression, I might see some interesting results. I mean race M3's with stock internals, stock intake, and no cats w/ 3in. exhaust make over close to 500 BHP with standalone and race fuel. Right now I am at around 395 BHP. Hoping to get at least 25 RWHP gain.
