I put it on and it didn't work right And pulling it off was a pain I cracked it Which really sucked so I sent. It back to jet to see if it's jacked up on the inside if the PCM was messed up hopefully it's the programming on th PCM that's not right. Because I want to see what this thing can do dammit. Sucks when open it theirs no returning it

I noticed an annoying exhaust note change when the AFM would kick in. The range device corrected that problem instantly. Product seems to well constructed of solid materials. I haven't had a chance to check any mileage changes but at this point I am satisfied to have the engine at full power. The truck is more responsive to the throttle.
