IMO the fast let off, depends on tuning, and how fast your IPR functions. With the adrenaline I have noticed being able to hold 2400 psi in my highest setting, held to the floor. It doesnt matter how it reacts when your off the throttle, or letting off. What matters is whats capable when your heavy on the throttle, in a high setting.

A little off topic... What is it when you let off the gas and it sounds like the engine quits running... Then as you slow down it sputters back to life. I never experience the engine cutting out under power, but only as it rolls or goes down a hill.

Robin, I have done many passes on my original stock 15* pump and never saw that spike. I would have freaked out. Like you said, it can't be good for the rest of the stock system. I converted to a stock 17* pump several years ago and I can hold 2800 PSI @ 45% DC on a 120 tune, but I still have the original single shots from the early 99.

I would like to know if your ICP spikes after the Adrenaline install. Did you order it wth rebuilt IPR or not?
