Testimonial Chrysler Reviews

Having just had the remap done, I can confidently say that there is a noticeable difference in how the car drives and accelerates. Given it's a naturally aspirated engine, I was impressed by the gains quoted by Celtic Tuning and can confirm the benefits they bring, if only slight.

The reality is, you're never going to get a massive difference from a non-turbo vehicle, so don't expect a large change in performance because that won't happen. Instead, enjoy better high end grunt and a more responsive drive. Would definitely recommend.

Had an ECU remap performed today by Kevin from Celtic Tuning. I had waited over 2 months for a slot but in under half an hour the car was ready to test and I was staggered at the difference in the power delivery.

Before remapping the car was always sluggish at low revs but now revs freely with a broad smooth power band. Transformed is an understatement!

If you have a Chrysler 300c diesel look no further than Celtic. It will be easily the best investment you make for the money and highly recommended.

Wow Celtic - thanks very much for a fantastic product and superb service! Stage1 remap giving my 300c 465 ft/lbs of torque - epic is an understatement. From the ease of booking by Rachel to the absolute top notch and punctual work carried out by Kevin. He was chatty and shared a love of BTCC and so we had plenty in common. He installed the new map but diligently had a look for any fault codes. He found the dpf was partially blocked and tried a forced activation but couldn't and so reset the dpf system. As soon as the car was started it went into regeneration mode - this was all put down to customer service! I could tell Kevin was really enjoying his work and remained enthusiastic and very professional throughout. Kevin is a credit to Celtic tuning and as a front line member of the team is 100% an ambassador and exemplar for service. The car has been transformed and is an even greater pleasure to drive. I looked at 6 tuning firms and am so glad I chose Celtic tuning - if only everything automotive was as good, honest and genuine. Thank you!
