the stock fuel system runs out at about 18 psi, which is also the max the OEM MAP sensor can read. Get a wideband in the car to keep an eye on the AFR before you start messing with the boost.
DO NOT just throw a 3 BAR MAP sensor on the car. The S1 PCM is not calibrated to read on a 3 BAR scale so it will cause all sorts of problems.
I have no experience with the PTP spring, but the AGP WGA should be more than capable w/o it.
Just my 2 cents.
: The max that the OEM MAP can read is actually 17.5psi. and anything above that can yield an overboost code. Honestly, the best thing to do (for maximum tunability) is to make or buy a return line with a nice AFPR (Adjustable fuel pressure regulator). After that, investing in a Diablosport Predator and a GM 3BAR MAP will help out tremendously. (This is the expensive route). The cheap route would be to buy a MAP clamp (after you invested in a return line) and tune it with a wideband.
Hope this helps. And like the mod said... Do some research!
