I have the 3865 and the trans tune if you put this on your truck,you will hate it if you have to drive without it.......when i take mine to the dealer it sucks to take it back to stock and see how the transmission ran BEFORE, I completly forget how bad it shifts stock, cant wait to put it back in when i get home so i put it back in at a store parking lot, its great how you can remove it and put it to stock take it to the dealer and they dont say a word about it, my favorite thing about it besides the trans tune, is to be able to run 87 octane when I want to and shop around for gas, BUT ,still leave ALL the goodies like top speed limiter off and the trans tuning on, rpm limiter etc,you cant go wrong with this tuner, the data logging is great, check your quarter mile times ,and then if you get a check engine light you can see what it is.....as well as checking sensors if you want to. this is one of the best mods I have done to my truck and you can really FEEL the difference when you put it on 93 performance tune. YOU NEED TO GET ONE OF THESE!!!!
