I used tdi last year for a remap on mine. Very happy with the transformation.
They will check the oil and coolant before hand. As they told me my oil was over filled. Which I do on purpose.
Other than that, the only sort of health checks they could do, would be compression test, check spark plugs, valve clearances. None of which I'd consider part of their job. Certainly not unless the cost was substantially more. I believe the owner should be happy the car is in good health. Or why are they modifying and mapping it.
As for customer service. Yes, it could be improved. But it wasn't bad by any means.
I think they are just very busy, and are inundated with the same questions everyday from loads of people. A lot of people will waste their time, or be looking for essentially free remote diagnosis.
They also need to get the work done, so while as a customer. We would love to be involved, and chat, and ask a hundred questions. They are running a business. If the next customers appointment time is late, because they spent too long chatting with the previous customer. One will be happy, and one won't. It's a fine balance to strike. And there will always be unhappy customers no matter what.
Paul is very knowledgeable, certainly knows his stuff.
I can't speak for Romain, as I haven't used him. I can tell you why I chose tdi though.
You can find vast history of what they have done, lots of high power turbo builds. Race and time attack cars etc. They also have mapped for oem, spoon, and other garages that claim to remap, but just send it to Paul.
They seemed to me, to be more involved in design and development of kits and products.
Also they are an in-house tuner. Rather than subletting to a tuner, using someone else's dyno. That's not to knock Euro or Romain. They also have a good reputation. That's just the reasons I made my decision.
