Has anyone used one of these? I’ve been thinking about removing the muffler from my truck (sounds pretty damn good to me for the price), and will want to disable the AFM (switch from 8cyl to 4cyl mode) if it drones on the highway. Range AFM deletes are somewhere around $200, and I can get the inTune i2 for $270. Is it worth the $70 extra? Probably, but just wanted to get some feedback and see if anyone has used one of these. Thanks!
