This is the third car I have had mapped by Celtic tuning and it's by far the best. The difference between stock and the modified vehicle is, in a word, outrageous. It's a completely different car.

I later had catless downpipes fitted and returned the car to Celtic for sensor deletion and another dyno run. Always happy with the service and advice offered, facilities are state of the art and you can watch your car on CCTV during the process.

I've just completed a return trip to Vienna via Germany and Holland. Needless to say, the German autobahns with many unrestricted speed limits gave me a chance to test the capabilities of the re-mapping.

The additional power was very useful for competing with some of the "bully boy" tactics that German drivers with high powered cars used to try and intimidate other drivers - I could easily accelerate out of the way much to their surprise!

But, the best surprise for me was the return on mpg! I completed 1852 miles on the trip and returned 35.2 mpg. I generally cruised at 80 mph with occasional bursts of over 100 mph. Town and village driving was generally restricted to 25/30mph. The weather was reasonable with not too much rain and temperatures sometimes reached 22C but generally cooler about 12C. I had winter Pirelli flat run tyres on 18-inch wheels supplied by BMW which gave me quiet running and additional grip. Most of the trip was completed in the Eco Pro setting (2 wheel drive) with Comfort setting (4x4) when roads were wet or cold.

All in all very happy with what you have achieved for my BMW.

One if the best thing I have done, so happy thatI did this, what a difference it has made, you canfeel the difference straight away andthe power it gains it’s just amazing from308BHP to 400MHP under 800NM of torque, the car feels so much smoothernow and they also said you get 10% increase offuel consumption but I haven’t managed tosee that yet because I am still lovingthe power the car has now.

I willhighly recommend them, I’mso happy I did this.
