Sorry no bs here. that's all correct. boost gauge works fine. I ran pump gas with octane booster at 25psi. i had set the boost to 15 and it over boosted to 25 but had safe RICH air fuel ratios at below 10.0 and sounded fine. i was in the middle of a 3 lap run so i let it run but was careful (no...

Here is a list of the mods and management systems:

I have it on a safe tune right now at 10psi and its probably only making 270whp or so. once i get it street legal this week i will turn the boost up to the 18psi that its built to run daily. For racing it will be on roughly 20-22 psi.

I picked up a 88 mk3 a few weeks ago for a pretty good deal. it was well built but nobody ever got around to tuning it.
small list of some of the mods...
Wiseco forged internals, 3.5" turbo back exhaust, 3.5" intercooler piping, custom aluminum intake manifold...
