A substantial production of entry level kits have been produced for this platform. While we’re happy to simply provide a tune, we’re also available to help you upgrade that kit to run more boost, add cooling, change fuel, etc. We have experience tuning ESS twin screw and centrifugal kits, VF centrifugal kits, AA rotrex superchagers and GPower superchager kits.

This product is the tuning only.
