last week when i was tuning on my truck it was 95deg. i dont have any gtechs but i do have my scan tool. my 0-130mph was in the 10.4sec range. a little later i raced that bike and it was 60 deg and it was way faster. scan tool showed 9.3 0-130 times. it felt like an easy 100more hp just from the temps.
