FWIW
I did send money to Kieth and he did send me the product. As a matter of fact I was undecided as to which module I wanted so I sent $25. 00 and ask him to send both. I recieved one in a couple of days and it took several weeks before I recieved the other.
The modules do what they claim and that is fool the ECM into not defueling on boost pressures over 20. 5 PSI.
With the maximum module and a DD wategate elbow, the turbo sounds like an electric motor and the truck goes.
