I have a full bolt on '99 Z28 that appears to be down about 30rwhp. It doesn't feel sluggish or have any ignition problems, but it definitely doesn't feel as fast as it should be. The car only puts half a car on a stock '00 SS car.

Any ideas? I don't have any weird noises or ticking sounds... I'm really baffled. The Throttle cable is opening fully.

It was tuned with EFI Live about 4 years ago. Is it time for a retune or something?
