Alfa Romeo Giulia 2.2 Multijet II 180 bhp

Hi, just a quick note to let you know the car is running faultlessly with more power everywhere. The work you've done has transformed the way it picks and pulls through the gears.

Many thanks for the work you've done, it was first class.

Your man was here prompt and on time and he was extremely competent, informed and professionally so please make sure you pass on my thanks.

Great service end-to-end, and from the brief run out in the car, plenty more power from the remap and a racier exhaust note in dynamic too, over all I am very happy.

Had the remap of the ECU completed in May 2018 by Cameron. A process that from what I saw was quick and painless for the Brera.

Once completed and taken for a short run, I noticed immediately the difference and the added performance to the 'sleeping engine'. It has become more lively and immensely more enjoyable when my right foot nails the pedal.

Cameron was able to talk through the process and answered questions in a professional manner. Well done..

Will be taking the 2.2 Brera out on a more longer run at the weekend. Thumbs up to Celtic Tuning.

Where you don't have the funds for a 3.2V6 or a compressor upgrade for the petrol engines then this upgrade will do nicely.

Delighted with the service supplied by Celtic. The upgrade map applied to my Alfa Romeo Giulia has improved performance, fuel economy, and makes this great car a joy to drive.

Can't fault Celtic Tuning, a lovely bunch of skilled professionals, great job!
