Your rev limiter is there for a reason, leave it alone unless you engine has been worked to utilize more engine revolution. For that you need better internals and bearings
been using it for more than a year now... Trust me when i say.. u don't need it really... You will get bored of it after a few days.. It won't fark your engine, it usually depends on how often and how hard you use it.. If u set Gain to F and at low rpm's.. then you are asking for trouble..
i had used the search button b4 but cant find something i would love to know ... anyone here can highlight me the 'pro and cons' of the 2 types of tuning ... thanks
