Ive been told its critical to turn off the afm on my vehicle to protect the longevity of the motor. I put the range device on and it did what it was supposed to do, im now in v8 all the time. I felt no differences in driving. Hopefully it will help over the long haul. It was cheaper and easier than getting a tune so Im happy with the cost and ease of it to meet my goals.
