Well put me down on the list for not being happy with the 1704 I bought, as I sent it back to yall at least three times complaining of surging, and bucking as if it was getting no fuel. Each time I got it back it did'nt run right. You're tech support told me my turbo was bad which I believed until the ford house could never find anything, and it ran fine stock. The good folks at innovative got me taken care of though with a great running sct, so I got a $400.00 superchips paperweight sitting here in my office! And boy do I have something to sell back to you. You got a credit card number I'll make you a deal on it and have it off to you within a day.
