Need help tuning for 90mm TPIS... I'm just wrapping up my 427 install and need help to get it safely running. It's getting a custom dyno tune this friday. The shop that's doing my tuning is 30 miles away and I'd like to drive it there. I'm running the 90mm FAST with the 90mm TPIS throttle body. The throttle body does not have the hole in the throttle blade. Where/what tables in LS1 edit do I need to adjust? Thanks for any help.
BTW, I currently have a tune for my old 422 iron block I'm trying to use, but won't stay idling on it's own.
