i have a 65mm pulley and what was a live mapped jabba chip. PM me if interested. My mate fitted a 65mm pulley and the car wasnt running great, so he made a copy of my chip and said the car was flipping quick after. I put mine back to a standard pulley/chip because I wasnt bothered about extra power and would rather have the longevity of the charger
I'm running a set of PSD toothed belts on mine, and a standard pulley/chip on another, the third is a turbo
