I am on my 7th 93 octane tune from Torrie. This one is bery smooth, linear, and poeerful. Once I get the meth strapped on he will fine tune it some more, hitting 18 psi with tune and boostmax at 50%, out of fuel. Tranny shifts nice and hard, breaks tires loose or the 1-2 shift and a bark on the 2-3 cooler days. I had Torrie tune my Focus ST before the xsport. I feel you can't find a better tuner IMHO.
