Worse on hot days. - Got Z? 23:23:00 12/30/03 I feel better about my very conservative 91 octane program. - Chip(GMS Racing) 10:56:20 12/31/03 I have three semi melted pistons from running 18 psi - MikeH(Twin GT35BB Incon Z) 14:25:10 12/30/03 Agreed.

(n/m) - MatD 13:15:37 12/30/03 Personally, I read every response. - Stealth021 13:31:01 12/30/03 Here's some food for thought too >>> - AshsZ(In Florida) 16:38:51 12/30/03 It seems from my reading that tuning for a/f is - MikeH(Twin GT35BB Incon Z) 16:58:56 12/30/03 Yeah, my ears...
