I had my LHD Pathfinder in the UK, so I decided to get it remapped.

Celtic did an amazing job. After remapping it I had a turbo problem (not related). Celtic went above and beyond to assist and ensure I was not left stranded.

It turned out there was a blocked oil feed pipe to the turbo that had been there for some time. Once that was repaired the remap could be explored properly. A great job and the extra power is really noticeable. This was just a stage 1 remap, and I can't see why you would need to go any further than that.

Thanks guys! I'm on the way in later today with the Audi TT for remapping now. I can't wait to try that one out on the Autobahn in Germany next week!

I have just had my 2.2 DCi tuned and EGR valve mapped out. I had already made a few physical modifications. Blocked the EGR valve, removed the rear exhaust box (dustbin) with a straight through pipe (no extra noise, there would be if the cat is removed), and a few other small things. They all help in making it smoother and helped the turbo kick in lower in the rev's.

The tune was done by Simon from Hayling Island. I removed the ECU for him, and 2 hours later it was all done, and of for a test drive. This is definitely a big improvement. The engine pull hard from as low as 1,500 and just keep pulling right up the rev's range.

I am not one to thrash an engine, but it is there if needed. As to it's drive-ability, it is just magic. So smooth to drive, and with so much more go. Tick over is no louder, if anything a tat quieter.

So definitely 2 thumbs good.
