Tony who does all of our tuning and tuned my E55 is going to handle it. I personally dont do any tuning, but Tony who does all the tuning for BIP is sending Jack a tune.
I have never had that issue with my car, but my combo is different to most on here. I have the utmost confidence we can get it fixed.

Unfortunately, there are multiple things that can cause this issue.
Injectors - If you have changed the size of the injectors
Throttle Body - if you have changed the size of your TB
These can go hand in hand. If you are cruising under partial throttle and tip the throttle slightly do you go rich or lean momentarily? If you do then possibly throttle tip in parameter could be tweaked to fix this. For example if you go to a larger TB, the amount of air that suddenly enters the IM is more than stock, the injectors may not provide enough fuel momentarily and will have a lean condition in which case the dTPs parameter (in an AEM for example) can help.
The same is true for injectors, for larger injectors, if the pulse width even though reduced, the initial opening time can contribute to rich or lean condition depending on the characteristic of the injector being used.
I cannot claim to be an expert tuner, I am not .. but i have set up a number of custom AEM applications from scratch in the past and encountered similar issues, so can only base on my previous experiences with standalones.
Many tuners that modify maps on OEM ECUs modify the injector and ignition maps only since those are easier to find. The more sophisticated ones will be able to play with injector offset, accel fueling etc .. it's not easy to find these other pieces at all. It'd be interesting to know how much of the ECU information in our cars is available to our tuners.

There are several of us that have logged the hiccup at constant throttle so I'm not sure this is what's happening...but I like the line of thought.
Has anyone actually linked this to the TB? To me that just never made sense and seemed to be more coincidence than anything else. I think it's more of a tuning virus. Tuners have copied each other's tunes for so long that we have a bad tune getting passed around under different brands. I'd like to see a tuner start from scratch and build a tune based off a perfectly running stock tune instead of loading their base and tweaking for mods.

Good post Turbo.
I was pretty disappointed to come back to this platform after being away for a few years to find that not a single advance had been made when it came to tuning.

We have sent the initial file to Jack this morning, and will work with him to change any parameters he wants altered.
Keep us informed brotha!

I still have the hiccup occasionally, but it is noticeably more difficult to trigger with this most recent tune I have from LogicLab. I do think we are barking up the right tree, but I have hit a snag with my MyGenius (I hate the name of this device, BTW). It "failed" to upload my most recent tune and the device is stuck in recovery mode. Since this device is made by an Italian company, we have to wait for them to send us a software update.
Craig, have you all ironed out a tune for the fixed pulley yet?

Denroll I'm glad it's better than before but like you said you are still getting it, by talking to a few guys it seems that motors pop while cruising etc which tells me the hiccup has caused this issue and also in your first motor. Turbo may be right on injector offset or partial throttle parameters

I did get it yesterday, but that was the first time in about a month. I commute through the mountains, but don't always drive the E now. Before, if I so much as even looked at a hill, I'd get the hiccup.
Side note: We need a new way to upload tunes. I should be able to stick some files on the SD card that is in my DashDAQ and upload it that way. Have you seen how easy it is in a GT-R? Craziness!

I am hoping to install the new tune tomorrow and will report back. I am opptimistic. But, even if the tune does not resolve the hiccup, I appreciate BIP and Craig responding to me and this thread. :-)

Yes report back brotha, we will give you several revisions once you install it to try different tip ins etc.
I do have a 82mm t/b; 1000cc injectors and 320lph fuel pumps along with my tune and have never got that hiccup.

one thing Dennis and I figured out is for the harsh cold starts, dont start the car right away. get in the car tap keyless go twice to without your foot on the brake to get key position two.
wait 30 seconds then use key to start car.
Car should start fine, no crazy lean condition or code and i avoid the hiccup altogether while driving.
This is all on Jerrys last tune to me for my FSP tune. It is still a bit rich but 95% hiccup free, not trying to get greedy but its frustrating.

It's one of the "personality traits" or idiosyncrasies of the fixed pulley. We were getting these ridiculous cold starts and the cars were pretty much not able to be driven at anything more than 25% throttle or it would just cut all fuel. Even then, it was scary lean. It would happen whenever the car was sitting long enough that it required a cold start. The only way to clear it was to disconnect the battery for about 10 minutes, then it would start normally. I foud out that if you let all the pumps and random German wizardry prime itself with the key in position 2 (or press start button twice with foot off the brake) before cold-starting, then everything is all fine.
