I am not a spokesperson for Superchips.
No one said you were - this is just a general discussion, with some "home truths", which some peeps find difficult to accept.
For the record, I don't have any connections, commercial or otherwise, with any company or product either.
I believe there is margin of error in all products, including Oetinger etc.
You are absolutley correct. However, it is the "width" of the margin that should be questioned, and with SuperSh!ts, that width is about as wide as the Atlantic Ocean! And don't forget the lies that SuperChips quote in their advertising! And what about any independent quality testing - SuperChips has none, Oettinger has TuV.

I'm telling you, people use REVO and then their DVs pack up.
And . . . a DV is quite a bit cheaper than a $hagged turbo, where Super$h!ts seem to excell.
Also, TT, I do not know much about remaps, but don't they all in the end mean increased boost pressure?
Fine - I'm no "expert", either. However, I do understand the requirements, of ALL the various functions of an engine management ECU. I understand the importance of multi-layer 3D mapping, and also dynamic mapping, not only for the obvious fuel delivery and ignition, but also "requested" throttle, "actual" throttle, WOT parameters, requested boost, actual boost, requested advance or retard, actual advance or retard, knock sensing, knock parameters, ambient air temperature, induction air temp, coolant temp, oil temp, EGR mode, lambda values, ancillary loading, battery voltage - etcetera, etcetera. What all that basically means is there is a whole raft of infinately variable parameters to adjust - even on the basic VW OEM maps.
Your comment on boost pressures - like I said in the above paragraph, increased boost alone is NOT enough, to correctly and FULLY alter a map successfully. Yet, I state again, all the evidence proves with little doubt, that SuperChips ONLY increase boost. And that, in the medium to long term, is a recipee for potential major component failure.
I kinda like the power/torque curves of Zuperchips, I don't like spikes like others have.
OK, fine. I'm not trying to tell you what you should and shouldn't like!
However, regarding spikes - two issues, and it may seem that I am completely contradicting myself. Firstly,
some spikes can be good, but only in certain circumstances. And the amplitude, or size of the spikes must be small. Spikes with the depth of the Grand Canyon are not good. Why are spikes good? They allow tyres that are struggling for traction to momentarily regain grip, hence regain traction. Spikes are best used on vehicles with no Traction Control (TC) systems. They can also be used on cars with relatively "lax" or liberal TC systems, such as on the GTI, and most BMWs. Spikes are a bad thing on cars with early intervention TC systems, such as modern Fords, Vauxhalls, most scandanavian originated cars, and general mass-market family or luxury orientated brands.
Secondly, SuperSh!ts also have spikes. They have big spikes on cars that don't need spikes, because of the cars early intervention TC. A classic example is a non-turbo Vectra GSi (complete with early intervention TC). When I carefully studied overlay dyno graphs, firstly I noticed that both power and torque curves had more peaks and troughs than a Hugh Heffner bunny girl party (yes, that was my quote, from a previous thread on the same subject), but there was also a dramatic loss of mid range power/torque. This wasn't a development map - this was their final finished map, to go on sale to the unfortunate paying public.
But hey, if you like SuperChips, then go with them, and enjoy (whilst it lasts)!
