Testimonial BMW Reviews

The Efficient Dynamics model in stock form is painfully slow and extremely dull to drive. I was initially sceptical of having a map installed at home, especially at such a low price but I am over the moon. The performance now is best described as OEM plus-it feels relatively stock even at medium throttle. It’s only when you put your foot down that you really get maximum power and the delivery is extremely progressive. Having had a much more expensive Revo map on my previous car, I can say the two are quite similar in how they come on.

I’m also of the impression that partial throttle now runs a leaner fuel mixture to boost mpg on the motorway. Highly recommended and a must have

Hi Guys, having collected the car yesterday afternoon I thought I’d give it another day before getting back to you. All I can say is “WOW”. The previous cars you’ve remapped for me have been non-turbo, n/a engines so no significant changes. The M2C is almost a new car with its stage 1 remap. Significant difference. Brilliant!!

Absolutely blown away by the Stage 1 map by Celtic Tuning. Beautifully smoothed out under comfort driving and at a flick of a switch turns into a torque monster that pulls hard and fast! Outstanding performance! Looking forward to replacing the tyres and breaks every week 😉

Utilised the eMotion2+ home tuning unit to apply the Celtic Tuning map to my 125d. The car already had some shove, but boost in torque really enchances the response and performance, especially through the mid-range. Request for minor tweak to map supplied within 2 working hours! Superb service, highly recommended.
