@amartinez...
Well I read someplace that Bama could tune it out. But I have an extended warranty -- and in California it wouldn't meet smog regulations. I'm still tempted though. I think the computers, fuel pump or A/C is more likely to fail before the basic power plant.
I had the Perelli P-zero tires stock. They were junk. Once they had about 4000 miles on them they would chatter violently under heavy throttle -- even in second gear when they were cold.
BFG summer comp tires were a huge improvement. They hook up well. I would rather have this throttle problem than those Perelli tires. There was no way to accelerate hard until hitting 3rd. gear. and that was even before I added the intake system and cat back.

Will do research this time... I have ended with a couple of things I regret: a useless (both cosmetically and functionally) rear spoiler. And... wait for it... Pirelli Sotto Zero winter tires... holy crap, DONT get these, overly expensive and useless... I’m literally drifting around in slomo the whole city. Yeah, no, in my experience I can’t say that Pirellis have been a good.
Thanks for the suggestions. Time to get on it.

I too have a 2017 GTPP with the Power Pack 2. I have that horrible stumble right after 2-3 shift. I raced stock cars back in the day and SCCA before that, so I am old school like everyone else. I'm not sure there is ANYTHING you can tell me to convince me to leave the throttle matted when I stab the clutch and am already shifting at/near redline. So I have been rolling into 3rd as if I'm trying to keep the rears from spinning on takeoff. Same concept and rolling into the accelerator as if there is an egg underneath. Sometimes though, I'd just like to stab it! I wish we could remove the NLS from the tune.

Maybe the forum moderator could forward this to someone at Ford Racing with the authority to say yes - instead of just obfuscating the issue.
This should be an embarrassment to Ford people. It has made me take pause in considering any additional Ford Racing products.

So, what happens if we remove this crap tune and go back to the original tune on the car and leave the throttle body and air intake? This tune has made the car undriveable in performance conditions. I can't get a 1/4 miles or 0-100 time because I lose 1.5-2s to the stumbling on the shift. In all honesty, the Power Pack 2 ruined what was a very fun car to drive in performance conditions. It is still fine for cruising around town etc, but heck, if that was all I wanted to do all the time, I'd buy a Honda Civic, not a high horsepower pony car.

Well, if someone here is an attorney, or Paralegal, maybe we can have a letter sent to Ford Racing that we can all sign.
Not to be abrasive or anything..... Rather to let them know that there are many of us that would not recommend ever installing these powerpack products on a Coyote motor. Does that fit their ambitions? To have a product that disappoints and that creates problems for a sub-set of its purchases? All for the want of an insignificant fix.
I have learned that many people you encounter with a problem in business only have the power to say no. You have to get to a higher level to get the attention that's deserved.

Just like using less than 91 octanes would also be potentially damaging.
For 1/4 miles, I started using the thing actually, in my case I don’t think there would be a faster way to shift, it does feel a tad smooth since the RPM goes down for you... problem (ar least for me) is really on race tracks, can’t be shifting so wildly like that.
Bringing the lawyers: I think that should be last measure. We want to point them a mistake that seems to be an easy fix... Or we could be risking them deciding to stop offering such products for the consumer market?
