Hey, I'm a new guy from Canada. I have a 1990 Chevy Silverado, 5.7 EFI. I have put an Edelbrock manifold, cold air induction, Flowtec headers, mild comp cam, B & M Hi stall converter and shift kit on it. Truck computer handles this fine. I'm wanting to upgrade the throttle body to a holley 570 scfm aftermarket piece. Anybody out there done this? Any issues? Thanks, I look forward to hearing from you.
