I don't mean to be negative, but with the size turbo you're using and a stock CP3, I think you'll have a hard time breaking 650. Either way, best of luck to you :thumb:Lol well im gonna be the first dummy to try and then if I cant it ill just stay in my 600+ range until I get some more green backs to play with a duel fuel kit will be easier to get to and fix than doing motor work thanks Josh for the advice
