I just dynoed today after installing the 2.80 pulley, chip, and o/r x-pipe. Ill try to get the sheets posted if i can. The 1st pull netted
446.7 hp and 450 lb-ft the 2nd pull netted 456.8 hp and 473 lb-ft. By looking at the sheets the a/f was "real" lean. Im gonna get that straightened out and she will be alright.

Did you just do install and then dyno. I think you should install take it for a spin then dyno.These smart puters need time to adjust.
