any idea why my truck runs like crap when it sits for a day or 2. after 10-20 min warmup its good but seems to smoke alot and run bad. any ideas would be a great help. its a 05 f350 6.0l. 80k miles.
thanks
my suggestion would be the sct tuner with custom tune or just a plain Superchips Cortex that can be used in any ford. The Cortex on tow mode (40hp) does work good for towing.
