THe Zex looks like the best small wet syst. with the new fuel controller. Do I have to have any timming retard on my '02 Z, M6 stock, for a 100-125 shot? All I have is a cutout and a lid. Also I would like to install a 2nd Nox solenoid for reliability, is this easy to do with that system. I will have a window switch and bottle heater. Any other suggestions? I won't be using it much and not at the track. Just have to keep up with the new higher HP cars comming out. Looking for long time reliability, running stock tires and hope to not bust the rear end. Thanks for any help!

I think it is for every 50 hp you need to retard 2 deg.
