I bought a brand new gt2x kit from a company in american through awesome gti, i fitted it after i rebuilt my engine. I ran the engine for a 1000miles without coming on boost before dropping the car off at awsome gti to get a custom map on. Then it all started, awesome couldnt get any boost and could figure out why, they swapped everything until they decided it must be there map so they sent it chip wizards for the map! Months later the guy from chip wizards said the fault lies with the TURBO! so awesome gti got the car back to replace the turbo. The company they got the turbo off didnt want to no at all so awesome gti got me a new ko3s hybrid frrom turbo dynamics, car went back to chip wizards and got a map! all this took around 6 months! Cant say its a good turbo and that company is rubbish! sorry for the long post just thought i tel my story about a gt2x turbo
