After running my car on apr stage 2+ for the last year I decided to to give R Tech a try, as I've heard so many good reviews about them. My car was running good power already but I was interested to see what niki could do. On arrival he gave my car a good looking over and told me what was good and bad on my car, which I couldn't believe.for all you people running quantum screen wash on your meth kits its a no no.it doesn't make it run anymore power.it needs to be the proper mixed de ionised water and meth, so my kit couldn't be used. He gave me a 5litre bottle for free to try after I remove the screen wash when I get home. After changing my forge dv for a standard dv he gave it a power run on standard stock power, I couldn't believe it made 284bhp and 267ftlb. Then he uploaded a map on my car and give it another run, not long after he found a fault a with my fuel pump. He took it apart and found the piston wearing on the bore which was causing it to lose flow mid range though the run. Luckly he had a spare pump on site to help me out. With that sorted he ran the car again and found the flow to be there but there was still something wrong.after more investigation he narrowed it down to the fuel rail sensor. With that replaced he was happy with the flow. Then he could start to work his magic, after running the car and tweaking the map he was happy with the result. I was nervous as I've heard cars don't make more than 370bhp on his roller with standard turbo very often. When he told me it had made 382bhp and 392ftlb. I'm one very happy customer, he help me so much to make the car right. Just shows I would have never known about the fuel pump unless I'd took it to him. He not only made my car a lot better but also saved me from destroying my engine. Top bloke, as a friend says he is the yoda of mapping
