Ive got the power FC, but just to get her up and going for the first 100 miles or so I'll be running this hoss on the stock ECU.

First off s15 t28......... will my boost controller allow me 6-8psi? I dont know if its a 12psi actuator, so correct me If Im wrong.

Secondly, should I try and stay out of boost completely until its tuned?

The cams are mild....stock lift, greater duration, so the way I see it, I didnt completely rewrite the book, so I should be fine to boost.

Im going to drive it tommorow, but dont wanna baby the **** out of it.

I'm thinking that the minimum boost you can now run is 12lbs. What boost controller do you have?

does a factory s15 t28 come equipped with a 12psi actuator?

I have an AVCR

No, the S15 T28 stock actuator is about 5-7psi. I would leave it at that and just turn the boost controller off, or down as low as it will go.

and at 5-7 psi with those cams, will I be alright to boost hard under load?

6-7 psi on that turbo with those 256's......yay/nay?

I have AVCR so I can monitor injector duty cycle, and boost precisely. I also have an EGT gauge, but dont know what would be considered an unsafe EGT.
