It depends... I prefer to service the builds which I engineer and sell. I am also employed part time by CoolerExpress and am very knowledgeable regarding those units. However, if you just want to ask me some general questions about a Mach II GT and are not looking for custom rebuild/retune then go ahead and send me a PM and ask away.
Hi, are you a good person to talk to about Mach II GTs?? Many thanks, Tom.
