I've done some minor upgrades to my 7.3 (4" exhaust, K & N Intake, boost relief valve, ats ported compressor housing and wicked wheel) and sadly I purchased the Edge W/ Attitude before I heard about the DP Tuners. I like to play some (muddin and some smoking of the tires) but my rig is mostly a daily driver and towing my horse trailer. I'd like to cont. do upgrades and also protect my investment. My tranny is what I worry most about. I've heard that with this chip it has the potential to fry my tranny. Now I only drive it on mileage and will boost it to race if I want to smoke them then drop it back down but when I'm pulling my trailer (I'm on stock or tow) my SEL will come on. Before I got the edge I thought it was a boost problem but I know that's not it. When I towed last week I threw the light then took it to my mech. He pulled a code and for the life of me I can't remember what the # was but it was a code in so many words saying I'm asking more of my tranny than is recommended. If I slow down it goes off in 5 or so minutes. So is there anything I can do to beef up my tranny to protect it and what should be my next upgrade to my engine to help assure it stays protected. I would like to in time dump the edge and go with the DP but again I don't play too much. I'd say the hardest thing it does is towing and that's maybe only once a month. Any input would be great!
