Seems like the car is getting enough fuel...

This is a '97 LT1, LT4 hot cam, 1.6rr's LT headers, CA, exhaust, regualr bolt ons. The problem gets worse as the car gets warmer.

looks like massive KR(knock retard) Do you have the lt4 knock module ?

 

Yes, I have the LT4 knock module in the computer. The Knock sensor itself came on the '97 motor and the computer was a 95 Caprice computer tuned by Ed Wright to work with this one. I think the computer and the knock sensor should sink fine, right?

Maybe it will be easier if I attach the graphs.

 

Unplugged the knock sensor and took it for another spin. It still hesitates when warm in high gear...

do you have a good fuel system? buddy has a 96lt1, head and cam, had to change out the fuel pump and injectors and get it retuned, problem solved, it was leaning out to much in higher rpms.

 

Yeah, 255lph pump and 30# injectors. The A/F curve on the graph is flat at 13.0 for the whole run (see run #3)
