If its working for you, then run with it. My wife has an 01 Excursion with a 6" lift, 37's and chip-intake-exhaust-turbo...
Runs great, but if you are happy with the performance, a chip will only improve shifting and MAX hp a bit over what you have now. Try looking for a Valve body for the tranny, it will firm up the shifts and keep the temps down a bit. Also look for a TC lock up kit, eather one that is a plug and play or a DIY. Lock the TC up any time you are above 30 MPH and that will help both pulling power and tranny temps.
Where is your EGT probe? Did they install it pre turbo (in the exhaust manifold) or post turbo (in the downpipe after the turbo)? What were your MAX readings for both boost and EGT's?
