Well I have a Paxton novi 2000 and at cruzing speed every once awhile it surges I've heard that it is caused by a bad bypass valve but if you guys have different ideas why it's doing it please chime in thank
depends on if you setup is for a blow-thru maf or a draw-thru if you are running a blow-thru and not recirculating then you can run a bov if not then you need to run a bpv
