Hi and welcome to mightyram. Someone was building a serious truck before you got your hands on it. This thing will be a weapon when it's running right FYI they never came with a twin cam V6 TT engine - only a SOHC injected 3.0 V6. We have had a few members try going the twin turbo route. For info on that engine you may need to go to some specialist forums that deal with something like a Stealth 3000GT or 3000 GTO Mitsubishi to decipher wiring and sensor set ups etc. Post pics and ask questions as it helps members here to find answers for you when you're in a bind.
