Been in to see the guys today and boy were they busy! But what a day, had a brilliant laugh with them whilst learning a lot,they really know there stuff and then come away with a smile from ear to ear after they set my turbo up, then they sorted a map that was ridiculously accurate to what the car was requesting!! Highly recommend to any one wanting a custom map and a really quick car!!

Took my polo to get performance upgrades mapped it, and they have completely transformed my car. These guys really know what they are doing when it comes to remapping, such a friendly vibe and happy to answer and explain everything to me.

Extremely happy with the work carried out by DervTech! Went up for a health check and came out with a custom map after finding it was running a very poor generic 'eBay' style map and overboosting all over the place! Can't believe the difference since having the custom map! Massive thanks DervTech! I shall be returning later this year for lots of goodies!!
