i wanna kno how much boost i can run on stage 1 pcm , stage 1 injectors, on a stock turbo ?

You want the peak at 18 psi and you will only be able to get 15-16 psi out of the stock turbo above 5100 rpms.

ok . yea im set at 18 now i just just wondering if i could could go above that and still be safe

I wouldn't as you won't get much more out of the stock turbo with more boost. Also with the way pump gas is these days.

Just get 650ccs and the E1 or S3K with the FM Wga.

if your looking to find a few extra ponies try a tuneing device, more specific the DSP (and a WB if you dont already have one) that will give you the option of unlocking some hidden power. but be prepared to spend between 5-600 bucks on a WB/DSP combo

IMO you have the stocker maxed out and adding more boost or parts to an untuned car is like trying to start a fire with water, if you dont wanna spend the money just leave it where its at

what about stage1 pcm with stage 2 injectors on stock turbo? can i make it spike 20 and i dont mind it dropping back to 15 cuz all stock turbos do that.

Stay at 18 psi until you get 3 bar sensors. You'll need 'em.

When i had your setup i spiked 20 and fell to 17 psi for well over a year and then went big turbo... i also had a 75 wet shot on top of that...

Not really, they are definately a worthwhile upgrade but not NEEDED for that boost level
