BMW X5 xDrive40d 308 bhp

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.

I have had my 2009 BMW 330D LCI for almost 12 months. As usual with a second hand car there have been a couple of issues. I have had those sorted but the car just seemed to be missing something...

I contacted Celtic Tuning, although they are in the UK and I am in Australia they were extremely helpful. They put me in touch with their representative over here, Jay.

Jay was amazing, his knowledge of my vehicle was truly impressive, he is a credit to Celtic Tuning, very professional and informative, he was open and did not hide any of what he was doing to my car. I found out later that he was a master technician for BMW and Mercedes.

My car is amazing now. The power is insane compared to what it came with stock.

My car now breathes a lot better, uses less diesel, on a recent trip the car was down to 4.4 liters/100km and has a whole lot more power. I could only be happier if I had been given an M3.

Celtic Tuning Newquay
Fantastic worth every penny. Very friendly and knowledgeable staff, fast service and flexible.

Car is long distance weekly commuter, full BMW service history and a strong healthy engine to start with.
50mpg average @ 65-70mph (Southampton to Plymouth)

After Stage 1 Performance map.
60mpg average @ 65-70mph (Southampton to Plymouth), 70mpg @50-60mph average achieved on an eco run (Exeter to Yeovil)

The car now has better progressive power throughout the rev range, most noticeable from the lower end, making A-Road overtaking faster and safer with far superior MPG all round. Couldn’t be happier and have recommended Celtic to several friends and family already.
