Tony came to us with his 2008 Ford Mustang Bullitt which was completely bone stock at the time of arrival. We strapped her down to the rollers and put down 279.17RWHP/293.52RWTQ! With a competitors mail order SCT tune, the car put down 278.00RWHP/296.59RWTQ. The Bullitt Calibration from Ford is very good, so getting power mail-order is tough, and this is proof! The air fuels on the factory tune were slightly more conservative and rich, the competing mail order tune brought them up about where they should be, but didn't find any power in doing so. We installed a set of Kooks 1 5/8" Long Tube Headers with a High Flow Catalytic H-Pipe and loaded in our base mail-order tune for the Bullitt with Long Tube Headers. The first run was perfect air fuels, timing, etc! We put down 294.45RWHP/310.29RWTQ! A 15 Rear Wheel Horsepower gain and 17 Rear Wheel Torque gain from the factory! And it sounded GREAT!

wow that is pretty good.

I guess there is some real gains to be had by long tubes, so many different opinions out there about their worth. Good to see proven gains!

[Tillman Speed]

There are some sufficient gains to be had with long tubes. The problem usually comes into play with vehicles with larger intakes, delete plates and longtubes and VCT and Drive by wire have to be adjusted in order to take full advantage of those items.
