Celtic Tuning M5 F10

[mb26]

I realise PH is more of an Evolve and DMS zone, and everyone will recommend their favourite of the two, but has anyone used Celtic Tuning ?
I have had my own experiences of Evolve DMS Eurocharged and some less so well known tuners...not all good experiences..

Celtic are offering ECU opening remaps on F10 M5...the two dealers I spoke to seem pretty competent and experienced..

I am booked in for next week...

Will report my findings but curious to see if I will be the first brave PHer to go for a non DMS Evolve remap..

I'd love to see the paperwork in relation to the warranty !

They'll offer a warranty on their own gear, but not the BMW hardware.

No tuner in their right might would take on the warranty bill for a powertrain like that.

And at who's cost do you get the root issue diagnosed before any items are claimed/replaced?

As promised here is my own experience of Celtic So having turned up at CT cars, the local Celtic Tuning agent, I was a little nervous as the garage was a very small place with no sense of tuning or motorsport...just a normal 3 bay shed garage in the country..
However when I asked about their experience opening ECUs to tune, the proprietor told me they had opened more than 300 ecus so I felt better and left them my car...
30 minutes later I got a call from them saying that they hadn't realised there were 2 ecus and the price needed to go up...
It was clear that they had never worked on an M5, which they then confirmed, so I decided not to be their first and took my car home.
When I contacted Celtic and asked them to recommend another dealer with experience of the M5, they finally confirmed that none of their dealers had ever tuned an M5..... so I would need to travel to their place in Newquay....

Pretty disappointing, and perhaps a predictable outcome but at least others can learn from my adventures...

Why not choose the tried & tested route of DMS or Evolve?

Both have worked on many F10/13 M5/6's with fantastic results & reliable cars. My M5 was used by DMS to develop their Stage 2 tune & i ran that tune for near on 2yrs without the car missing a beat,
