Hi, I am planning on using my 94 Cadillac Fleetwood to tow a camper trailer. The diff. Ratio it has is at 2.56: 1 (not the best towing ratio).
I plan on upgrading to a 2.93: 1 (from a Brougham) to increase the towing capacity to 5000lbs. Will this affect the pcm? Is there a tuning that must be done to the chip?
