I had the juicebox on mine and it just wasnt acting right. It would stutter on hills, didnt want to stay running after a cold start up, and would shut off on a wide open run. Messed with the settings and it didnt help much so I got the PCIII and a map from Bo and it is a totally different machine. Driveablity is awesome compared to the juicebox. It still wont cure the hard start though, if you look at the battery, it is pretty small, the Raptor 700 uses a bigger battery to crank it over and it has less compression than the XX, I know they all have decomp for starting but I do believe a bigger battery would help, the problem is the small area it has to go in.
