AMD are a long established UK based VAG, and now Porsche & BMW business - no connection with the USA

Bolloc&s - my mistake, sorry. I was getting them confused with APR - a senior moment!
They have since been bought out by BigBoysToys and Mega4

Now that is bad. BigBoysToys are - well - like extended warrantys are to Dixons Stores Group (Dixons, Currys, PC World). They have a pretty poor reputation, especially with "hard selling". I just hope they don't drag AMD down. Do I take it that Mega4 are also part of BBT ?
I don't know much about APS and JBS so I can't comment on their skills or quality.
But it is their lack of feedback, either positive or negative, which should ring alarm bells. Afterall, the VAG 20VT has been around for a long time, and many many companies have good success with that, so why no feedback on the 20VT
Also, as I understood it, the GTI 2.0 TFSI engine has never operated with a stratified mode, either here or in the USA (correct me if I'm wrong) - I understood it operates under a permanent "homogenised" directly injected air/fuel mix, rather than a variable "stratified/homogenised" directly injected mix..so why would an American tuner be at a disadvantage to a European tuner, other than ensuring that the generally lower fuel quality over in North America is taken into account when building a map???
Wrong. All FSI engines, turbo or n/a, in the EU markets, operate in both homogenised AND stratified modes. In the US/Canada markets, the stratified mode is ECU disabled (due to their lack of ultra low sulphur petrols). If the stratified mode is not visible on their map, then how can they "re-map" it, and satisfy European mapping modes?
Also, don't forget, there are many different "operations" which
can be altered on a re-map. Those include turbo boost, turbo venting, fuel volume, fuel pressure, fuel pulse (multi pulsing), ignition timing (standard advance and retard, and octane upper threshold increase), variable intake manifold, variable inlet cam timing, WOT air-con disable, electronic coolant pump - and I'm sure I've missed some more.
Many of the "lesser" chip tuners simply increase turbo boost, and little else!
On the GTI, you are dealing with the Bosch MED9, and not the older, easier to crack Bosch ME systems.
