Thanks Dave. I spoke with Holley this morning and it sounds like the only way to really dial this intake in is to run the Holley ECU and wiring harness. By the time you purchase all the necessary items I could do a turbo system or possibly a SC.

My tuner told me I needed bigger injectors when we did the dyno run. What I have works but if I do an upgrade I might as well go big to cover future HP gains. I really want the SC but not sure I want to spend that kind of $$
