How far can I drive after I install the tunes befor I replace the stock exhaust? I know that it has to happen soon but, is it going to hurt my engine if I drive the truck from the parking lot to the mechanics bay with the lift to switch out the exhaust? The plan is get my stock file, send it to Ray, get my tunes, drive to the shop, park, upload the tunes and then pull into the bay and put the truck on a lift and switch out the exhaust. I am renting the bay by the hour.
Does that plan sound crazy? Should I just load it up in the bay, tune, and not drive it at all until the exhaust system is changed out?
