I was getting detonation at just 10 degrees timing with 17 lbs of boost with the mixture a bit on the rich side. No more detonation and I got a much smoother transition from no boost to boost and some more power to boot! Wish i had a dyno in my garage!!
Thanks

Are you using the ZZP Mini-AFC controller for the MAF adjustment? Just curious to see if you've had any trouble, or which version it is.
My biggest suggestion with the WI on your GTP is to go with an aftermarket intake and CAI, then remove the MAF and use a fogger nozzle at the bend of the intake pipe pointing right at the TB. I did alot of playing around with mine. I don't think the type of nozzle is as critical in a roots application, as the heat of the blower/TB rapidly evaporates the water anyway, and even if it didn't, the rotors wreak havoc with the water vapor.
Your M90 will naturally run a little cooler than my M62, as it turns slower than mine, so you're probably producing less heat than I am, but we should still have fairly comparable applications.
