Mike, I'll be in contact with you for this new kit. I have a customer in Saudi Arabia who wants me to buy him one for an '09 Tahoe with a 5.3.
Here is a link to an '08 Hummer H2 that we built for this same customer, in which he had us use a Magnacharger 2300.

The above system has given us a lot of problems in trying to make good boost with it, we're talking in the 14 psi range, and we still don't have it worked out. I'd like to give your systems a chance! Thanks. Bob
