Had the AC line rub a pinhole in the hot side IC boot. It just looked like a chafed spot on the passenger side boot. It blasted a hole in the hood insulation 1.5' above and would only make 12psi. Made 15psi after repairs but I'm 1st gen with a non wastegated H1C turbo-charger. 32 sounds high unmodded
You want MORE BOOST? Read here!
Explains there are 2 modds needed to pass the 20psi mark.
Tells you what to look for and how to undo/reverse engineer.

What are your EGTs running at cruise/ psi. Vs pulling a grade. What EGT corresponds to your 15psi?
For me its 1000°f=15psi. 1050 during turbo lag aprox 1-3sec.
Depending on wether 5-600° 1-3psi in the flats between Anaconda and butte.

Any one got a HX35 laying around I'm looking for a wastegated ehxsost ?
