if you are running premium fuel like u should be 17psi should be fine under stock injectors, you can do 15-16 to be safe, but with adequate spark and no fuel problems its realy quite hard to blow anything up since you will hit fuel cut all day long

 

fuel cut will require a change of paints the first time you hit it too. It feels like the motor blowing up or rear ending another car or something if your not ready for it you will go threw the windsheild hahaha I love that

 

What is the BCS?

 

1 PSI = 10 HP ???? is that true?

 

deoends on the turbo and supporting mods I guess but 10-15HP is a little close. I know stock 03 EVOS they claim a MBC at 19PSI will gain 20-30WHP and that is going from 16/17PSI stock to 19

 

Yea 15psi is pushing it on stock fuel. I hit 18 and cracked a valve... Needless to say I will never have that problem again with my recent upgrades. 15psi is kind of tough too. Mainly blowing hot air.

The BCS (cant remember what it stands for) is like a little pill like thing inside your stock boost controller. Supposedly someone gained as much as 3psi when they took it out and most get 1 maybe 2. What you do is find your stock BC (under your intake). Take the bottom of the two hoses off. Take a regular size screw and screw it in a few threads pull the screw out...should have a little plastic piece on the end of it. Basically it has a little hole it in put in the way to restrict boost to a moderate level.

*ANYONE PLEASE CORRECT ME IF I AM WRONG ON ANY OF THIS!* Its been awhile since I did that "mod" hahah

 

This has been a good thread for me...if i turn my boost up to 15 with the stock turbo,is it a worthy,noticible difference?if it is noticible,how much quicker would it be in the 1/4??thanks

 

it will be very noticable from stock. And depending on the mods you have it will either be less or more noticable. Like say if you have a catback youll add even more power because it will be less restrictive.

 

oh ok thats cool,i have an injen intake,3" turbo back with a hi flo cat,and a greddy front mount....sounds like it will be worth the $200 for a MBC and a gauge

 

WHAT!!!. How the hell are you figuring that. I would think about 20-30 for the MBC and then another maybe 60 for the guage. I dont think its more than $100 unless your looking at an electric boost guage
