Due to the odd nature of dynoing these cars, the highest numbers we've seen, and the only ones we compare against for product development, are from the Mustang dyno.
We are hoping to get on the Mustang dyno next week. The only one near here is very busy though, so I'll keep my fingers crossed.
I had an 04, and there was no limp mode, no codes, no problems whatsoever and speedinnovations made it so that my cars tc would fully turn off with the switch. call them, ill give you the number if you want.
