Apr 01,2018I purchased a Synergy 3 box and realised insurance wouldn't cover me for it. Tuning Diesels refunded me immediately after I contacted them. Very good customer service. Wish I could say the same for my insurance company.

Feb 14,2018Made a huge difference to the performance of my aging Land Rover Freelander TD4 with over 130K miles on the clock. Even better after I cleaned the inlet manifold and serviced the 4 fuel injectors. Worth every penny. Easy to install. Hardest part was finding a hole to put the cable through whilst fitting the cabin switch. Currently using setting 6. All good so far.

Jan 13,2018Old MAF was causing overfuelling and smoke in my ZT-T. The Pierburg MAF and synergy box has breathed new life into the my MG! I was thinking of selling it, but I might just wait another year or two now. Performance is tangibly improved, pick-up is better, mid range acceleration is way better than before, even when car was 20k younger! Haven't done the numbers on fuel savings (or othewise) yet, but the old MAF was clearly making the car inefficient, so I know it's going to be better. Even if it's only a small improvement, it's worth every penny for the extra OOMPH. Spoil yourself, buy a Synergy 2a today.

Nov 21,2017Fantastic . I have a freelander 04 td4. And the box and switch are a brilliant addition. Easy to fit . Step by step instructions. I find the dashboard switch to be a must addition. I also tow a caravan and find that using the switch on long hills a must . So easy to over take . If you are thinking of buying one , stop thinking and save money now by getting this .

Oct 02,2017Great quality product, easy to fit with no issues. The mg ztt cdti is now a different car supplying a superb amount of power throughout the power range, fuel consumption has remained the same as well.Worth every penny. I would strongly recommend this chip having done homework on various other ones available.Better to pay more and get it right first time than buying a cheap chip and giving yourself problems

Oct 02,2017Brilliant to deal with! The new maf sensor made one hell of a difference thank you.

Sep 06,2017Amazing from start to finish. Ron, the contact there (who may also be the owner) was brilliant, gave great advice and options, really knows his stuff. Delivery was great. The product is fantastic too, does exactly what it promises I got the synergy 3 instead of opting for a remap. And I am not disappointed at all. I've also got a dash switch so I can toggle between 2 modes, an eco focused one.... and an all out clutch slipping one.... actually I'm not using that one atm.... until the clutch is upgraded. In summary whilst I think "Ron" would benefit from allowing someone to RE-vamp his website, the product is top notch and you won't be disappointed.
