Car didn't gain any mph with 2.8 pulley because it didn't have time to learn /adopt to smaller pulley. I'm sure it would have been around 144mph on the next pass . They put the 2.8 pulley on other Coyote , similar setup but manual car . it didn't gain any mph on the first pass either then it gained 3mph on the second pass

OPG , TC and fuel system are the plans for winter time

Those sound like good items to take care of at that power level and with the amount of track time it sees.
