Hi all has anyone out there used a hypertech tunner on the 5.4?
I just ordered one and want to know what to expect.

Thanks

You still have the question? I would think by now you've recieved your order.
I just bought one the other day. I'm not as happy with it as I thought I would be. Did you lower your water temp as they recommend?
Did you switch over to the 92 or did you leave it at 87?
Let me know
