Just bought this mcx turbo machine. It likes to spit and sputter at half throttle. Back fires alot as well.. pulled the back seat I see there is a mcx box and two dynojets one is a dynojet comander v and a dynojet auto tune… is this how its supposed to be set up. Is there anyway I can check and see if it’s running right. Top speed is 70mph
