I have been told the only way to remove the cats on an '06 is to go into the computer and disable the 02 sensors that are behind the cats. Will any unit read a roush programmed ecu? This is on an '06 Mark LT with a Roush intercooled setup.

 

I doubt there is a calibration for a Roush flash. I've been told you can get the SCT guys to figure out what parameters are in your PCM if you have the advantage software and a programmer. If you got a programmer with your catch code, it's going to have the stock settings. You're probably better off working with a custom tuner that can accomplish the same thing. You'll probably end up with a better tune.

 

I haven't found anything yet, I tried with HP Tuners when I 1st got my Roush, I failed several times, even after several HP updates. I am just not ready to drop $700 on a handheld and a custom tune when I know the Roush Tune has been tried and works great with my 9psi. After 25,000 miles, my transmission is still holding up fine.
