Holy monstrous main jet batman! :lol: Sounds like you're on the right track though.
The only thing I'll suggest is to go in small steps on the PVCR holes. I went WAY too big and ended up having to plug and redrill, not a huge pain, but aggravating.
My turbo setup was very mild compared to what yall are running. Mine saw 10lbs only a couple of times with almost the same results ( tire smoke from a 25mph roll :D ) Even with my 6-8 lb setup the tired motor was a beast. Glad I can help, even if just a smidge.
You guys are an inspiration to us all! I can't wait to see the time slips from the track :cheers:
