How can I get 3 different stages of boost? I was thinking 7psi for daily, 15psi, 25-30 (not sure yet) so that I can still drive my car on the streets and have a little fun but not go overboard.

Also how would tuning be accomplished, wouldn't I need three different settings for my A/F and timing?

 

I believe turbo xs just came out with a 3 stage boost controller though honestly I don't know why you would need anything bigger than a two stage. One for daily and one for racing.

 

traction control....less boost in lower gears would help with tire spin

 

True, I guess I could just go w/ 12-15 for daily and 20-30 for race. That's probably what I'll do then... But how does that work for tuning. The needs for 12-15 are a lot less than 25-30, the risk of detonating is much higher along w/ other factors.

 

You can tune both pressure levels on the same map... that part is easy...

Then just use a boost controller to control the different levels of boost.
