Yeah it works really well for me. Interfaces with Bluetooth to my Iphone so makes it super easy to use. You need to buy HP tuners credits too, you need 4 for the Mach 1, all Gen 3 Coyote require 4 credits...
Is all that purchased on the Wengerd performance site ?or better site to buy it at?
I bought it all there. He will send you an email with a link for the credits, you need to wait til you get the RTD first, when you buy credits you have to enter the S/N of the RTD for them to apply correctly.
Yeah thats what I did the second time. I just had to have the RTD first, cause you need the S/N when you order them....
The credits, he actually recommends buying the universal credits from HP if you already have a RTD device... When I got my first tune on my 22 GT I bought it all from him, the device, credits, everything. On my Mach 1, I already had the RTD so I just got the universal from HP. Either way, same price on the credits...
