I have been consistently working on my car forever just as most people here and last night I finally got it running great. On top of fixing all the vacuum lines I decided to go ahead and try some 110 octane leaded racing fuel. I figured It might help because the increased boost and the gutted cat. I have been experimenting with different ratios of it. Last night I think I finally got it right. 5.5 gallons of 91 octane to 1 gallon of racing fuel. She ran like a champ last night beating an Accord and a Celica GT-S (barely with the GT-S)with BPU's a Saturn with exhaust intake a 50 shot (50 shot was rumored so I not positive but I did hear something like a solenoid and quick revs after that. And a civic with a bolt on turbo and not even an exhaust I ran dead even the whole way down. I was proud of my baby last night and just wanted to share the fuel ratio with you guys that don't have cats anymore.
