At UpRev getting the 370 Tuned

He installed five maps: performance, economy, stock, valet and theft. It is controlled with the cruise control switches. I was there for about five hours with about half the time on the dyno. Lawrence, the owner, spent about 45 minutes smoothing out the A/F maps on his computer. A couple of notes: the graph is SAE corrected (not sure if that is what everyone else is showing - uncorrected [actual horsepower] was over 300. The runs were made in 4th gear so numbers may be a little low. Interestingly, my car seems to like a rich mixture and when he leaned it out more it started to lose power. Also, Uprev is working on cam adjustments but that is somewhere down the road. My mods are R2C intake(with Modshack vent), Berk HFCs and smaller crank pulley. They use a DynoJet, model 248C.
