Testimonial BMW Reviews

BMW 2 Series M2 Comp 410 bhp Petrol

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.
