Just had the truck on BD's Dyno for the second time.
1st time = 239.0 RWHP @ 5,000 miles, only mods were K&N and updated computer program.
2nd time = 248.8 RWHP @ 35,000 miles, stock air filter (K&N was drying out after washing it)same updated computer program and semi-syn oil.

Hey Al, sounds like its breaking in rather nicely. ;)
It actually got broken in last fall on a hunting trip -- for quite a while there it was red lineing going up some really steep grades and it has been purring ever since. I think I will redo it again in Oct (BD dyno days again) with the K&N and summer fuel. I wish I had the time to take it back to the 1/4 mile track and see if the ET's have changed much.
