Please keep us informed VenomSVT and VenomGreg....I am working on an entire buildup involving the VCN-2000 to include ignition, timing, and fuel upgrades, but this kind of malfunction is really testing my dedication to the idea. I'd hate to spend $2200 on my car just to burn a hole in the piston on my first test run while thinking I am running at 5% nitrous discharge. Please let us know when you find the cause of the problem!!! Thanks.
