After installation I really didn't notice much difference in my gas mileage but the shifts and performance did increase. I am very pleased with the performance I received from the programmer and I'm glad I made the purchase.
It is working good so far. V8 MODE 24/7

I had oil some consumption issues from my afm. I have had the range device installed for about 500 miles now and my fuel mileage has improved some or stayed about the same and my oil consumption seems to be little to none so far which would've been 1/2 quart or so by now with the afm on. I haven't really notice any performance improvements but I never felt like my afm was causing any lack of performance just the oil consumption. I'm happy with my purchase! Thanks
