Hmmmm, if anyone thinks that is
good service, then I hate to think just how low you need to go for it to be classed as crap service!!! No wonder this country has gone to the dogs!

I say again - it seems blatantly clear to me that the Superchips product is CLEARLY UNDERDEVELOPED. Superchips are using paying customers as beta testers. OK, there was the odd occurance on an earlier thread, when someone had probs, they let him have it for free - but I doubt had he not have made such a noise on public forums, then it would have been a different story. I said it before, Superchips had problems remapping the much earlier Bosch "ME" ECUs, and it would still seem that they are still out of their depths with the Bosch "MED"s.
The ONLY reason why they are able to offer increased performance on the 2 litre FSI turbo engine is . . . . gentlemen - I give you more turbo boost. Much more turbo boost! There is no evidence, from examining their dyno curves, and also listening to testimonies from other users that they have done any else.
One final point, what "quality" accreditation does Superchips have? Answer - none! Oettinger products have TüV accreditation - and I doubt few would question the robustness and status of TüV approvals!
