I really think there isnt much point to going more than 15-16psi on the stock turbo. Those t25's are crap and are pretty useless going any furthur than that cuz your really getting out of the efficiency zone

 

Wow i been pushing 19 for about 6 months now on a t25 with a stock fuel pump. Wonder if my turbo is shot

 

if your car still runs good and has power you are probobly fine, I wouldn't do it anymore tho. I run 16/17 on mine with stock fule pump.

 

It is just as bad for the car as it is the turbo. when you go out of is effecientcy zone all it does is blow hot air and can cause detnation. at 19PSI on the t25 and stock fuel that is happening for sure. If you lower your boost 1 or 2 PSI the car will actually be faster.

 

probably shouldnt even runmore than 16 on the stock side mount intercooler anyway

 

First, sounds like you need to do a little research on the topic.

Now, you need to get yourself an accurateboost guage if you don't have one all ready. If you just want to raise the boost a couple pounds, you can do it for free yourself by removing the boost solenoid restrictor. Look up on how to do it the vfaq.com. When I removed my BSR and replaced my stock BOV (it leaked all boost at 13psi) it raised my boost to 16psi. I wouldn't recomend over 15psi on stock fuel setup unless you have a logger to log knock, timing, ect. So, I got a boost controller to turn it back down to 14-15psi untill I had the supporting mods for more boost.

You will feel the difference on just a few psi, so start with that. You may also want to do a boost leak check to make sure you are getting all of your boost to your engine. Hope that helps.
