Default hp est.

Hi guys i know yall have to get tired of hearing this .. so in advance i apologize ... just curious on what hp i might be pushing with intake 4'' exhaust and ppe boost valve and ppe standard only on 90hp tune right now ... im guessing some were close to 340? still new to diesel tuning and not sure what % loss there is from crank to ground ... have done lots of track cars and used but not much diesel ... i know the butt dyno sure feels around 350 and from what i have calculated i should be right around 340 ... just curious if my calculations are close and if some one with a similar set up has been on the rollers ...
thanks in advance

340rwhp should be close


I calculated 331rwhp with just the PPE at 15% powertrain loss
