Re: Project: Mavro Gato (56K ... Get a cup of coffee)

Drove the Cougar to work today ... it's an odd feeling being floored on the highway in 3rd gear and running the tach past 7,500 RPM before shifting. The previous stumble is a thing of the past. My hat is off to Tom for a spectacular tune. At cruise, the A/F ratio bounced between 14.2 and 14.9. At Full throttle, the A/F ratio stayed right between 12.4 and 12.7 ... too bad I have the turbo cut heads on here ... this thing would be INSANE with more intake velocity!

There is a dyno shop about 1 mile from my office and I'm hoping to stop by at lunch time to get 3 runs in ... if they have time/space to fit me in
