fswerks tunes are only box tunes if you just buy xcal2/3

if you do IM or turbo etc... then you get emailed revisions just like with tom.

yes, altitude and humidity are a big difference, but you do the data logging, and he makes the new file, all to get those AFR's running in the proper range. testimonial after testimonial from FSwerks guys, i dont think hundreds of guys from th states, yes even northern states will disagree that FSwerks is the best for the focus. Even @ steeda, pat told me he got all his tricks from randy on how to tune the focus ECU, more so the duratec because it is more complex.

Personally, i would leave it with the guys that know their stuff once you start putting more air in, you get what you pay for in the end. nothing against dasilva as im sure they are great tuners, but how many duratecs have they tuned?? mite be a question you ask before getting it done somewhere.

once again good luck and do a 5 speed swap you autotragic street racer LOL
