When I do get a boost controller, how do I know how much I can turn it up? At first I will have a boost gauge and an A/F ratio gauge, possibly an intake air temp gauge as well (right before the TB). With these measurements can I tell how much I can run? Can one detonate with the proper A/F ratio? Will an EGT gauge be necessary to measure this?

I think the HS kit runs 7psi? With your stock maf and 370 injectors I think you can get away with 7-10psi. It all depends what you maf voltage tops out at. You don't need to worry about water injection on the 9.5:1 cr until around 13-14psi? Someone correct me if I'm wrong

Good question. When you have that fule set-up the limitation is the turbo. The t25 is spinning its guts out at 14psi and is not recomended for daily use at those levels. The other limitation is the ignition, at 14 psi its about toped out also. With those up graded I'd assume you could pump out 20+psi but that is somthing I'm not sure about and I'd also like to know what the # are.

What is the limit for 8.5:1 cr boost wise before you need to start running race gas and or water injection with out touching the bottom end?
