ISX 871 525hp No throttle response

[Brock]

I'm a 306 boy myself. I moved out to Albert's now as I work hauling oil and I too had issues with these systems and my excessive idling.

Not to say that shop isn't going to do it right...
But from what I've seen, none of them do. I 100% guarantee you that they are a sub dealer for a big company who will do the work remotely and put some generic bullshit program in there that'll have your engine surging and pushing oil and most importantly probably end up over heating your head.

For a guy who idles alot like you do, there are parameters that can be adjusted to help keep fuel usage down and also help keep Temps up on those cold days and these are things you need, not some balogne 700hp tune that makes your motor run hot.

There's crop insurance for bad yields but Brad wall ain't gonna bail out stupidity.

Plus side is you are at the right place to get the proper help to make sure that motor makes you some damn money!
