"Recently purchased a whipple superchager and upgraded to the stage 2 setup. Car is 15 gt 33k miles. Switching from stage 1 to stage 2 for the 15 is different injectors, 132mm TB and different tune but same pulley size.\n\ncurious how many people are running a whipple stage 2 15-17 car and running 91 octane. No other mods to the car and no plans. How reliable is the stage 2 tune and 91 octane setup for these 15-17 cars?"
