just as the title says
my gf got me a diablo predator for xmas and i went ahead and installed the 89 octane tune on my 3.5l yesterday since i still have close to a full tank of gas of 89 octane. so far i am very pleased with the improved acceleration and much better shifts! i barely have to tap the pedal now for the car to actually move as to where before i had to apply quite a bit of pressure to move the slow tank with 22s lol
also it seems as if the car is now louder and also can really feel my airhammer at work now as well!
i cant wait to try out the 93 octane tune!
