Why the difference in torque & HP between the E series vans and the F series pickups? Can the van be brought up to the same specs as the truck or are there internal differences in the engine itself?

I don't have any proof but I have been told that the vans are downrated because of cooling issues. Occasionally, I have to road test a van with the doghouse removed... it feels like there could be cooling issues.

IIRC, the vans use a different calibration from the pick-ups. There is probably a way to flash a van PCM with a pick up flash. It likely wouldn't be easy and might cause problems (other than mechanical) down the road.

Vehicle programming is part of the emissions control system. In some jurisdictions, techs can face some pretty impressive penalties for messing with them. Strangely enough, Joe Average can get away with nearly anything.

Could there also be a space issue? The Powerstroke is shoe horned into a pickup, the van must be an even tighter fit. Perhaps intercooler plumbing is smaller/more restricted?

I often wondered about the difference myself.

I suspect that is one of the main reasons. Space is at a premium in the E-series engine compartment. On the 7.3L version there was no room for an intercooler and we even have a slightly different oil cooler probably due to space constraints. Also, on the 7.3L version one of the two batteries had to be mounted on the frame rail due to space contraints. On the 6.0L they did manage to get an intercooler on them, but I think it is smaller than the F-series IIRC and again because of space contraints they had to move "BOTH" batteries down to the frame rail. /ubbthreads/images/graemlins/shocked.gif Also, on the 6.0L E-series they even had to move the engine oil filter down below <font color="red"> LOOK HERE</font> which shows the FCM, oil filter, and tranny filter on the 6.0L engine. Notice the oil filter is upside down which makes for a mess when changing that filter element. I understand the fuel filter on the 6.0L engine is somewhere buried up in the engine compartment, but I think we've lost several search parties in trying to locate and gain access to it /ubbthreads/images/graemlins/wink.gif For those that have never seen a PSD E-series below are a few pic of the 7.3 and 6.0 configurations. I can actually get at quite a bit of my engine after removing some interference, but I would cringe at attempting that looking at the 6.0L doghouse view.

I can tell you it does get hot in there. I've already ruined one air filter box due to heat warping the oval area <font color="red"> HERE</font> where it attaches to the rubber intake track back to the turbo. My second air box started to warp and I have now covered that area in header wrap to try and protect it better.
