I just got my chip installed on friday i ordered
40t
65t
80 dd
100 per
120 race
im very happy with how it runs i havent used the tow setting yet. Tomorrow im going to put the tow to the test. the 100 and 120 both surge so i have to figure that out.. The only problem i had was with the switch. I mounted it in the dash put the knob on and when i would turn it, The knob would start to get harder to turn untill it tried to trun the switch itself. I made a phone call and found out as you turn the knob it goes in slightly so i had the knob in to far so what i did was turn the switch to the highest setting all the way to the right then installed the knob..

Thanks for helping me today,
One very happy customer

Good deal bud, the wicked wheel took care of my surge. You can get one for $75 & put it on in about a hour if you've never done it before.

Is there much difference between the 100perf and the 120 race? I dont know of many people that have both. I have the 100perf but am considering having the 120race installed at some point.

IDK Bob I've got & really like the 120race but kinda wonder if I would really be able to notice a difference, interesting question.

Unless you want more smoke on the bottom end, there isn't any difference.

Really Cody, I would've expected a bit more power and maybe different shift strategies?????

well havent used the 100per yet its been stuck in 120 so far ill try it out tomorrow and let you know. I did get to use the 40 tow I was at 19,600 gross. it pulls very nice revs kinda high i think.. 3K before it shifts not sure if thats normal.. but the 40 hp with that load helped alot im very happy! i had to pull a big hill and it started surging bad then the truck down sifted and it went away. On the flat parts it ran 70mph at 2000 rpm Ill keep updating..

The 120 does call for more fuel, but whether or not you get more power depends on the truck and the condition of the fuel and oil systems.

Realistically expecting more than an extra 100-110 RWHP out of stock AD injectors is kind of .

I have single shots and both 100 per and 120 race tunes. Honestly not a huge difference. 120 smokes more and seems to shift harder.
