i had my truck on the dyno a couple weeks ago. We were looking at the sheet and noticed that my HP and my torque spiked up about 30hp and 35ft lbs. it was a smooth incline and then shot up when she got around 4200 rpms. then it went down and leveled off again. just a quick spike. does anyone know what that could be? i do have a fairly new stall converter. and a recently rebuilt and beef'd up tranny. but im starting to wonder if it has to do with the tune.. any suggestions would be great.
