sams email is
sam@gtmpower.com
FYI can't go wrong with GTM. I bought my twin turbo kit from sam and I would do it again in a heart beat. Great customer service and the man is always reachable no matter what time it is. (I don't think he sleeps LOL)
After you review his instructions give him a call you will find that you wont be disappointed.
