I have a VX XU6 and wantto upgrade to your 10 psi pulley kit.Also are there any other items that I can buy in conjunction with the boost upgrade

Below is what we usually recommend to start you off. However, these don't have to be installed all at once. 1. 10Psi Boost upgrade kit 2. 1.90:1 ratio rockers 3. Cold Air Intake kit 4. Cooler thermostat* This combo will get you around 35rwkw (more if accompanied by a free flowing exhaust) for around the $1000 mark and comes with simple step-by-step instructions such that it can be fitted by even the common DIY enthusiast. NOTE: Extractors are not recommended at this stage. *Please note that the thermostat is difficult to replace without removing the supercharger and may not be a high priority at this stage unless the supercharger is already being removed for whatever other reason.
