Read the reviews prior to purchasing and some mentioned battery run-down if not driven daily. It's true, pulled my truck in the garage at 4:00 p.m. Friday afternoon. went out to start it to run uptown at 4:30 Sunday afternoon and battery was dead. Remove RANGE if vehicle sits for a couple days. Would have given higher rating had it been worthy of it. Battery drain is unacceptable.
It does exactly what I bought it for
I bought this to turn off the afm on my truck and it does exactly that. I have also been able to read an engine code with it already as well and worked great. The reason for 4 stars instead of 5 is because it seems to mess with the truck electronics while installing the tune (dash lights flashing, service stabletrak), which I don't know if its normal or not but worries me, so I will just stick with the stock tune with the afm disabled. Autoanything was extremely helpful with the purchase.
