I have a 2000 camaro with 5.7 turbo, made 817 rwhp on 16-18 lbs boost on 93 octane pump gas and ran 10.2 @140 mph in 3800 lb street car with bres 9 plugs, why is it when I put a tr55 plugs in it the car picks up and ran a 9.45@148 mph?did not dyno it with tr55. Any ideas would be appreciated

Boost/AFR/spark/knock logged on both passes? Same gap on both passes? Sounds more like you had a crack/defect in 1 of the BRES9 plugs and replacing the entire set gave you full 8 cylinders again.

plugs too cold, don't know if id run stock plugs but could definitely run TR6's

No way in hell would I run 93 octane only at 800whp on a TR55 or a TR6, just asking to torch a piston.

This is like the 5th time I have done this to prove myself to some tuners, it ran for 3 years with the tr55’s on 93 octane and ran 9.14 @152 dozens of 1/4 mile passes ! The bres9’s were all good no issues, but now it did burn a piston with the tr55’s in it

People get away with a lot of **** if only running 1/4 mile. Try the same thing on a highway pull or road course and boom.
