I must be missing something... So he dynoed 270 originally, swapped TBs and came back another day, 270 again.

Came back a different time only switching to BP gas and now 318???

Guess I am a little leary as they were different days, temps, etc. Could have been a bad batch of gas or something else... I guess a better test would be slap the car on the dyno on BP, tune, drain all fuel, switch to holiday, and tune again. Still hard to rule out temp of the intake charge and the possibility of getting bad gas...
