performance chips for Excursions?
Does anyone here have a performance chip in their EX? If so what year/model is your EX and which brand performance program do you have?
We took my EX somewhere to have this done, and they couldn't get the Bully Dog brand to work at all. The guy said it had something to do with the security program of the EX? Apparently it's different than that of the F250's. We went back 3 or 4 times, and he kept trying different codes the company had given him, all to no avail. Anyhow he did get another brand (sorry, I don't know what it was) to work..sorta. It runs fine at stock, runs even better at +40hp, but at +90 and +120 it shifts oddly. I thought I would see if any of you had success with a performance chip in your EX.
