...a great bloke with a serious skill-set in mapping! Managed to get a 43bhp increase and an extra 10 Lb Ft of torque! Can't recommend enough!



...could not be happier with the results from only minor modifications. More to come, will definitely be back soon.



Top bloke, long drive from Yorkshire to Birmingham and what a drive back. Definitely knows his stuff, will be coming back.

Had a custom map designed to suit my Astra G 1.7dti 16v eco4 fitted with uprated intercooler and hybrid turbo. Amazing up lift of power from 75bhp to 136bhp. Still runs strong with very little smoke. If you want excellent service, this is the place to go!

Been running kd maps on both my cars for years and never had an issue. I own a 334bhp vectra vxr and a 200bhp astra Sri and both cars have been fantastic since Dave mapped them!

Had my Vectra Z20NET mapped by KD with pop and bang, made a massive difference and i was very impressed.

David is a really talented guy when it comes to this remapping also more besides. Fitted me in around my work even on a sunday. My work van is so much better since having the work carried out by David from KD CUSTOM TUNED. Cant wait to get our other vehicles done. Cheers mate

I got in touch with this company looking for a custom map file.. I was very specific about what I wanted, pops, bangs, launch control ect.. Over the course of 2 days, they created a few files for me to try, and adjusted and tweaked them as I requested, they went above and beyond to make sure I was happy, and the support and communication was excellent.. My vehicle already had a remap which cost an extortionate amount of money from another tuning company... And I have to say the map that KD Custom Tuning provided me, made the other company’s efforts look poor! The noticeable difference is unreal.. I highly recommend this company and I will certainly be using them for all my remapping needs in future
