I am in the same boat. Not sure the dealer will even let me through the door let alone a flash the truck. I havent updated mine because i have had no issues other then the slight knock.

ya my well get the ax flash diverb before hand i got it when when i had my dpf delete and chip really didnt notice much there was a slight increase in mpg and seemed a bit smoother running but i have egr delete on now no issues what so ever and doing the egr delete wow was a huge diference for my truck runs way smoother and it actually quieted the exhaust down a bit for some reason but i have way more turbo whistle

OK, will do. I called the dealership and will get the AX flash done on Wed, and after that I will install the EGR plates.

yea my EGT's dropped about a 100 with it. It's alot larger than stock and that was one of my first modds before the DPF delete. Now that I have the DPF gone, my EGT's are great. I cant wait to get rid of that EGR. That darn EGR is the devils work!

oh nice yeah i would take any egt drop i could get but right now with that egr gone she doing good you might have to post some egt temps after egr delete since you have that intercooler on there mine cools down to 300 at idle after driving...pretty quick but getting there faster would be better

The AX flash seems to solve the knock issue for those that have it.

It should be written on a sticker under the hood.

If it was last week it should be the AX flash, it's the newest flash version.

All the ones I have had on my trucks have been under the hood near the fan shroud by the hood latch.

Not all dealerships are putting on the stickers.

Also, they might put it down at the ECM.
