I dynoed my 93 this past weekend, mods are in my sig! Operator said it would have made on the upper 280's cooled down and leaned out, it was full operating temp and the A/F was in the high 11's range around 3500 and rose to 12.6-1 by 5800, way rich! He said it needed to be in the 13.5-1 to be ideal, so I guess my next mod is a custom dyno tune!
