I had a Celtic Tuning remap done on my 2007 Grand Cherokee CRD a couple of months ago. I have owned 7 diesel vehicles previously, had them all remapped or fitted tuning boxes, and the results have all been good, noticeable improvements in quietness, smoothness, grunt and power - never regretted them.

The remap to my Jeep however - has been simply astounding. It completely transformed the car. It now drives like a different vehicle. So much more pulling power throughout the rev range, overtaking is a pleasure rather than a chore, no peakiness, no flat spots, no plumes of smoke.

Celtic Tuning claims an increase to 290 bhp which is difficult to believe, but the way the car performs - it's now difficult for me to doubt. Best money I have spent.

I had the Stage 1 remap to my Jeep Wrangler administered by Celtic Tuning’s Cameron as a mobile service. Cameron was very professional and talked me through the remap, explaining each stage.

The result has been excellent. The throttle response is much better and has removed the sluggishness, the torque is much stronger and the whole engine / drivetrain is now very smooth; a different vehicle. As a bonus, the mpg return is about 10%-12% more efficient, especially on longer runs.

I recommend this remap and I really should have had it done earlier!

I had my jeep remapped around 6000 miles ago. Wow what a difference! Now it really goes, especially excellent when towing 3.5tonne trailer. There is loads more power and torque throughout the rev range.

I absolutely love it and would recommend. Mpg is slightly up on what it was by 1-2 mpg. Excellent service and very helpful staff who don't pressure sell, all in all very good and greatly improved drivability.

Thanks Mark

Just got back to South Devon: what a transformation! Pick up and throttle response both markedly improved, in gear acceleration is noticeably better, low speed pick up is excellent and, with a direct there and back comparison on mixed roads, mpg went from 27.5 (there) to 33.1 (way back).

An excellent outcome! Quick, efficient and courteous service as well, what more could I ask for!
