So i was trolling along and spotted this company. They even state to offer an upgrade to motronic 4.4 which I was even more interested in. And they offer retuning for cheaper. Anybody tried them? I think I will before summer, after rebuild.

snabb ECU upgrades

 

look at the ECUs, they are ARSD tunes, just offer in conjunction with SNABB parts.

 

ARD teamed up with Snabb so Snabb is selling the ARD tunes.

I was a M4.3 and am running the M4.4 conversion from ARD. Its been customized for my setup. One thing I noticed right when I cranked the car for the first time is there there was absolutely no delay in starting. It was instant and I even put my IPD tune back in to try it again. Others have seen this too. I put the M4.4 back in and instant start. Its amazing. Lucky says there is much more code in the M4.4 so it can really be fine tuned over the M4.3. He is thinking of only offering the M4.4 conversions for M4.3 owners. He is also working on remapping the transmission control unit.

 

Another +1 for SNABB and ARD!!!
I still have the manual 4.3 stage Blue tune, but once I get the chance I too will be going to the 4.4 ECU
