Ok so I bought an already deleted and tuned l5p. Truck was set on a tow tune no light truck ran great.I just got the rest of the tunes sent to me. I attempted to install the sport tune today. Now I have an engine light with an exhaust fluid message and a 95 miles until 65 mph top speed. I have no clue what I did wrong but I need to fix it ASAP. This is my daily driver so I can?t really have this going on. Can someone shed some light here on what I can do to fix this?
