Isn't the stock intake plenum the max limiter of boost we can go with? |
That's not a question that can be answered without a lot more info. 25 psi out of a tiny turbo is a lot less air than 25 psi out of a large one. The motor may hold up fine with 15 psi out of a gt28 and explode at 15 psi out of a gt42.
