I know its not fuel it starts around 6000rpm 11-12psi. Not a bad break-up but for sure not right or good. Anyone else have this problem. Wondering if i need more ingnition. Further more i want to change my rev limiter, and the box will help for that. I would not mind having the BTM as well, but then again i never have had detonation.


Anyone know where the problem is at?

 

I'd run some race gas thru there and see if the problem continues. If not, then you could be running to much timing for pump gas.

If you still have the problem, look into the ignition.
what are you currently running for your ignition system?
What plugs, what gap?

 

MSD coil, NGK TR6 gaped @ .35. and MSD wires. Ill go and get some 100oct if this FREAKIN RAN STOPS.. The timing issue is one that i was thinking about. Thats one of the reason why i wanna get the BTM. Thanks for the input

 

I had similar issues which turned out to be a bad opti. I replaced my setup with LS1 coilpacks to eliminate the issue.
