guys, you all understand we sell ECU and not turbo kits. we have all the necessary testing done to say the 800 arctic cat ECU is working flawlessly and we have incorporated a MAP sensor on the main board so you can save some installatlion/harware money.Now, if a particular turbo manufacturer is not doing his job, then it ain't our thing, while we are helping a few guys straightening up their stuff, it takes some time and commercialization need to be adressed. Again, We sell ECU and no turbo kits, we are willing to help the best we can but won't let go mapping on our side until satisfied with the hardware.....the push turbo kit is running good but need a few tweaking to make it stable that we are adressing with Ken right now. Hope this clarify the situation.
