Sorry, was busy grinning:icon_ford:....All I can say is WOW!!....This is the biggest bang for the buck you can get for your 7.3!... Got him 80DD,100perf,120race, whisper, and ss.. The first three are bad ***!..really woke this truck up!...shifts are not hard, it just pulls like a freight train, 120 race sets you back in the seat and makes your teeth highly visable. Whisper just idles it down and cuts the outside eng noise by I would say 30%, and it seems to be a nice feature if you do alot of drive up stuff. Smoke Show did nothing. Neither one of our trucks smoke anyways, even full throttle. He set it on SS, waited a few seconds, reved it up..nothing. No biggie though. I can see where you would pretty much leave it on 80dd about 95% of the time. If you see one of your buddys at a red light..flip it to 120Race and blow his doors off. Install was straight forward. The only thing that was a PITA was having to pull the chip three times to rebuff the pcm contacts. I was so paranoid about removing too much of the tin, I didn't get a good connection the first couple of times. There is ALOT of silicone on the pcm, and I had to use some acetone to get it all off, rebuff with the scotchbright pad, and all was good. I just didn't want to buff it down to the copper, and ruin a pcm. DO NOT attemp to start your truck up without a WTS light verification, if you don't get one, it aint gonna start. Take your time, pull the chip back out, buff on the contacts some more, put it back together, get a WTS light, fire it up, and prepare to have your mind blown. HIGHLY RECOMMEND!!......Aaron. P.S. like Jerry said, just cut the back of the case out to prevent wire pinching, or forcing the chip in too far. P.S. Ordering mine today!")
