How did nitrous get such a bad rep...?
It's ALL in the tune on anything. Why can one person get a car to run 120 and another gets the same car to run .1-.3 and 2-3 MPH faster. It's the tune and hook.
Nitrous is no different. Base deal. If the fuel jet is the same size or larger than the N2o jet, it's a junk tune at the plate. Too much timing KILLS more juice engines than juice itself (back to the tune up). Run safeguard, fuel pressure switch, window switch, etc to try and protect the engine. Same as a rev limiter, it's there for a reason.
