You will need to monitor your logs of course but you can add 3 to 4 gallons and shouldn't have any problems. That will also make a big difference.
Thanks! This is exactly what i was looking for! Just still trying to understand for myself if flash tune will be better or jb4 and if the results are pretty close then jb4 might be a nice option since i can unplug it anytime.
