Dyno question

Hey guys, picked up a 2010 F-250 4x4 CC a few months ago and will be taking it down to get it dynoed for the first time this Saturday and had a couple questions. First off the mods I have is a 4" MBRP exhaust, S&B intake, and a H&S Minimax tuner. I currently have the max boost defuel set to 39. The problem is I hit defuel fairly easily just making a brisk pass on the freeway. Should I turn it off completely for the dyno runs or just raise it higher? Secondly, should I be doing a 4th gear pull or 5th? Thanks for any help you guys can provide! I'm still amazed at how easy and cheap it is to bump up the power on these things!

I would turn it off, but if you want to keep it on set it at 50. As for the dyno, pull in 5th, or at least thats what we have always done here.

Will do! One other question. Is the 5th gear pull ran all the way up to redline?

Doesnt need to go all the way to redline, but they will take it close.

I think it depends on the dyno operator. I have heard trucks sound like they were about 50 RPM from coming apart and had others end the pull as soon as the curves fell off.

No go on the dyno guys. Apparently they can't do diesels for some reason. I thought they were pretty much universal other than for awd vehicles. Piggybacked off of the local BMW folk's dyno day and was looking forward to killing their numbers! Oh wells, gotta track down a place that dynos diesels now. Thanks for all the tips guys!

Some dynos intercept the coil wire to track rpm's... Would be kinda hard to do on our rigs..
