Harley have 6PSI which is why there not the 380hp there what 340 or 360??
Lightning has 8PSI stock, but if you put a K&N Panel in you could boost closer to 9PSI, at the track i have a K&N panel and a bunch of holes cut in the bottom of the air box, and i decided to take out the filter for a few runs, and i was boosting close to 10.5!!

yeah i didnt think they were but if it is correct i wont be complainin to ford about my extra pound. No mine is probably just off. At the risk of sounding stupid, If you install an autometer boost gauge they are correct so why are out stock gauges not. .They connect to the same spots right. is the needle just not accurate or is it getting some kind of wrong reading. Just curious. I dont really know how the boost gauge works.

My stock guage has been close enough to tell increases. How accurate is mine above 8 PSI, I don't know. Mine read dead on 8 PSI bone stock. If you mod the airbox with a K&N you will definitely see an increase in boost.
Click on the link and scroll down to see the results I got with the stock pulley. The only other mods were a 160 stat, sparkplugs and a Magnaflow muffler. I almost forgot the boost actuator adjustment gave me close to a 1# of that increase. With the bigger pulleys the boost actuator adjustment is barely noticable.

The factory gauge probably cost somewhere in the $1.50 to $2.00 range
