[QUOTE="earico, post: 10786539, member: 114682"] +1 A fuel system is something you should never save money on. Supra guys do long 150mph+ overdrive pulls all the time. With factory cast pistons! Been there and done that myself. Had one for 7 years. Are you guys not putting enough buffer in your tunes? If you tune for an A/F of 11.8 in 4th gear on a dyno there is no way in hell you still have a 11.8 on the street at 150mph in 5th gear. I'm new to Terminator tuning. Is heat soak worse at the higher speeds? Is the blower pushing hotter air at 150mph? If so can we tune in enough fuel to cool the cylinders at high speeds? Is there a way to have injector duty automatically increase when IAT2s increase? [/QUOTE]
