Will be a while before it sees any serious boost. I have my lite 5psi spring in the WG for now. But eventually I’d like to take it to 10-12psi like I did with the last combo on this gt45. I’m starting my tune all over from scratch with the new combo, plus my ECU went bad on the Fitech. They replaced it and I don’t even want to attempt to load any of my old tunes on the newer ECU.
