This kit is the ultimate in octane boosting! I use a 75/25 mix which is conservative and makes great power. You can adjust when it starts to spray and when it maxes out. The controller also allows a hookup for stand alone ecu management systems if you don't want to use the stock computer. 25 WHP gain on my stock turbo. Even more with the upgraded turbo. Good Buy!
