I have a 93 with a Denny T pin, 3200RPM spring, and 4" exhaust, K&N intake, with everything else stock. I see about 25psi of boost. Someone was telling me that they thought I should be seeing highter boost. What do you think?
Thanks.

 

Have you tinkered with pump besides the pin? I would say 25 is good with the stock turbo. I have similar setup but 2nd gen intercooler and highest I see is 25 to maybe 27. You won't see too much more with out a compressor wheel upgrade or smaller housing.

 

Sounds about right if those are the only mods you've done to a bone stock truck. Mine would barely make 20psi on a good day, if I was lucky.

 

I agree, without any pump adjustments that's about right.

 

Thanks for the quick replies, I just was curious if I should be looking for leaks, but it sounds like I am right were I should be.

 

With what's in my sig i'm hitting 27-30.
