I don't like fuel cut off....because when I set it up on my S10 for the "abuse limiter" at 3,500 activate 3,450 resume it would NOT hold the rpm like I wanted and at WOT it was reaching 5,000rpm....Violently shaking the whole truck...but still revved past the set limit.
I dunno maybe I had a leaking injector or something...
IMO the safest and best way to get launch control is deffinitly Electronic throttle body..
Super easy to set it up...and safe because it literally just keep the throttle blade from opening all the way at a set rpm.
