I went from PG to Turbo 350 last summer in the Corvette. 60' picked up .09 and carried it to the finish line in warm weather. In the cooler weather, the ETs are about identical, even though the 60' is a lot better. I suspect the engine combination didn't like the RPM drop at the shift in the warmer weather when the power is down. Oddly enough, the car seems to be even more consistent with the Turbo 350, which surprised me as the car practically xeroxed time slips with the PG. Reaction time picked up about .03, which was the main reason for the swap. All this is with a 3200 lb car with a 650 hp iron headed 427 with the same converter. The Turbo 350 was built by a local builder with good parts, but it is no Pro Trans.

I will say that it is way more fun to drive with the Turbo 350. Went from barely lifting the tires off the ground to going on the bumper. Had to put the wheelie bars back on!
