Fiat 124 Spider 1.4 MultiAir Turbo 138 bhp Petrol

Highly recommend the remap carried out on my Fiat Spider Lusso. Increased hp from a stock 138 to 199.6, Power is smooth through the range and has greatly reduced a flat spot which it had when starting off in 1st.Had a before and after dyno session at the Derby branch where the staff were all very professional.

I just wanted to say what a difference the remap has made to our 16-year-old motorhome.

It feels more powerful right through the gears and going over the downs is not the gear change challenge it was. Even my wife came home today and said Martha is going along easier. and the service was 1st class.

Had my fiat 500 retuned by Celtic Tuing and what a big change to the 500 its so much better to drive the extra power and torque to the engine has made it fantastic to drive.

I have great pleasure in providing a testimonial for George Williams Geewiz Diagnostics technician with Celtic Tuning.

George remapped my Fiat 124 Spider, a complex and difficult job requiring the removal and opening of the ECU. To say that this job was complex is an understatement. Using state of the art equipment skill and determination George successfully completed the job. His care and attention to detail and knowledge was second to none. I am seriously impressed by George's skill and have no hesitation in recommending him and Celtic Tuning to others thinking about remapping their car.

The change in the cars performance is astonishing.
