Any idea what the air temp was in the shop during the dyno pulls? Mine put down 629 in November with 60deg iat1's, but only 576 with iat1's at 113 at the beginning of each pull. You could have been pulling 4+ degrees of timing depending on the temp and if your tuner messed with the iat spark tables.
