I just wanted to send you a quick note to say thank you for the successful remap on my Fiat 124 Spider, the car has a much improved response now, exactly where it matters in road use. Both torque and power seem to be delivered much more smoothly so the car now feels like it should. Thanks also for the 'bonus' of your special December offer, which made my day! I have already posted on the 124 forum how happy I am with the remap and hopefully you'll continue to get more 124 remaps going forward! Thanks again.

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.

Thank you to Kev from Celtic who did all the work!!!
