Mine would do the same with a new tune, almost like the adaptations are causing the issue??? I just either nail it up the hill or use cruise control and no hiccup for me. I almost never get it anymore because I adapted my driving style.

Update: BIP sent me the new tune. But, I was not able to download it. BIP uses the Galletto ECU Flasher 1260 Software to flash/dowload the tune to your ECU. You have to first download that specific flasher software to your laptop (and the laptop needs operate on Windows XP or Vista program) and use that specific Flasher (OBD cord) to flash/downlad BIP's tune to your ECU. If you do not use that specific Flasher (OBD cord), then you will get this error: "Writing Initilizationchanging speed error Seed key... errore SK1". I just ordered that Flasher/OBD cord and once I get it and use it to install the BIP tune I will then further update.

Update: I am still awaiting delivery of the needed Galleto ECU Flasher 1260 (OBD cord). I paid $20 for it to be overnighted on feb 11 and still have not gotten it. I can not reach anyone from the website that I ordered it from. It turns out it is a Hong Kong company......the wait continues.

Few basic parameters that are adjusted in most injector scale tunes. battery voltage latency is an important change to look at , when going with larger injectors. even voltage drops can change AFR and the ECU needs to ahev the right parameters set to cover our daily voltage changes.
"Injector slopes, breakpoints and "battery voltage latency adjustment" to cover the behavior of injectors. Slopes represent the flow of the injector at high and low pulsewidths. Breakpoints determine the pulsewidth required to switch from the low slop to the high slope. "

The reason the tune changes after 50-70 miles, is that we need our "long term fuel trims " turned off or set to 0. The car only needs short term trims to make quick changes. So even after you tune or custom dyno tune, the LTFT will keep adjusting the AFR, so you may end up leaner or richer after 70 miles than at the time fo the tune.
Few basic parameters that are adjusted in most injector scale tunes. battery voltage latency is an important change to look at , when going with larger injectors. even voltage drops can change AFR and the ECU needs to ahev the right parameters set to cover our daily voltage changes.

Open-Loop, especially when going WOT should use the maps the tuner has written into the ECU, i dunno how much the STFTs and LTFTs influence the open-loop maps at all though.
But anyway, so if i understood you right, the hiccup mode is the tuners fault? Do you have the hiccup mode anyway exotic-metal?

Mine has been hiccup-free for thousands of daily driven miles now, with no changes to the tune after switching from the 82mm tb to the 90mm tb. This was after the hiccup code would occurr at least once a day, sometimes 10+ times in a day.

So you didn't retune after going from 82mm tb to the 90?

Update: I am now at 112 miles and no hiccup and no P0106 code. Still crossing my fingers. I will update more after some more miles.

Between yesterday and today, I put 130 miles on the car with the new BIP tune. No hiccup, no P0106 CEL and no pending CEL. I will continue to up to 300 miles. If no problems after 300 miles, then that - to me - means I no longer have this problem due to the new BIP tune.

I was curious as to what mods they had, what tune they had, what tune they tried, was the new tune's AFR changed. I have never heard of this hiccup / P0106 issue coming back after 6-700 miles of no problems.
