Boost ???

[White99GSX]

I have a question I just installed a boost gauge to check if i am losing boost and at full boost i get 15psi in every gear but it seems to drop off to about 13 and it holds steady there is this normal?

In the 2g DSM's the turbo is slightly smaller then in the 1g's so as you approach redline its normal to notice your turbo is only good for about 13 psi or so. If you want to hold 15 psi u can probably do so by freeing up your intake and exhaust lines, but if u want more boost then your looking at a turbo upgrade.

also an aftermarket blow off valve would help alot becuase your stock 2g blow off valve wont hold boost to save its life

sorry i forgot to add that to my post I have a k&n fipk rre upper I/C pipe and Greddy Type S and Hacked dump iwas wondering if it was normal for it to peak and then drop off silghtly

Ok I have a question. How much boost should you be able to hold near redline??? My car can hold 15 psi near redline from 1 and 2 gear but from 3rd-5th gear it will drop off around 4k. Is this normal???

yes, with the T25 it is

but with a 14b it should be able to hold 15 psi right up there in high gears as well right??
