Magyver

Hey I put the pills for the wet kit according to what the directions for NX says, but I'm running lean when I spray. I was hearing detonation occasionally when the car hits 210 when I've sprayed and also slightly below that mark. I would have to make sure the car is cool before I spray. Well I dynoed again today and I'm at 314rwhp on 1st run and 315rwhp 2nd run. 3rd run I sprayed and was lean @364rwhp & 392rwtq. I am going to go back to the dyno next weekend and experiment with the fuel pills. Has anyone had this problem? What fuel pill are you using if this is so?
