Well the temp was in the low 60's and air was ok took my truck to a local end of the month dyno day.

Got a new best:

397.5 rwhp
483.5 rwtq

Just need to get to the track when it opens up and get some real times.

Only mods are JLP chip and 15 lbs of boost.

 

, so where does that 15lbs of boost bolt up to?

nice #'s though. so close to the 400/500 club

now for some times!

 

were those the corrected numbers?

 

Yes.
