Yes I've used Trackhound.
He mostly maps existing Newage ECUs I think. (Saves buying new hardwear and rewiring)
I was doing some gentle ignition advance tests on my Classic with Apexi PFC and he gave me some great help.
Then when I went 2.5L and bigger turbo my MAF needded a full recalculaton - the car was running like a dog. Trackhound (AL) mapped it for me and the power delivery is smooth and awesome. I also have half the knock noise showing on my Apexi commander screen that I had before and learned loads while going along for the ride. Thanks Al - nice work!
