Oh yah, well when I had my vornado with my esc (electronic super charger) the butt dyno could not even read the Hp gains. I call it the supervornado, they told me that I could not run at the track anymore unless I was towing a taco cart. I was runnin mid 11's with the taco cart but all of the time slips were uuuh ,,,, lost in the flood. But really really really, the chips and vornados do work, just dont use them with a supercharger or they will make you race pulling a taco cart. F5 baby, the finger of god.
