Where have you been?

I have asked repeatedly on these forums if anybody knew if the E-series 6.0 was mechanically different internally, or just programmed differently. I had one salesman, of dubious authority on the subject, say that the van 6.0 engines had different crankshafts from the trucks. That was more than a year ago. Most others disagree, but not many of them are sure.

I have also asked if anyone knew how the van 6.0 will respond to performance modules and chips, specifically, if a module claims to add 60 horse to a truck, will it add 60 horse to a van?

My 2004 van has 235 hp and 440 ft-lbs of torque. The 2004 trucks had(?) 325 hp.

If I put a chip in my van that claims to add 60 horsepower, what will happen? Will the engine try to produce 295 (235+60) or 385 (truck power level of 325 + 60)?


The threads in which I asked these questions have long since been lost in obscurity. I could dredge them up again, if it would be helpful.


The van intercoolers and intercooler tubes are smaller. The radiator may be smaller. The air conditioning system operates two cooling coils. The intake draws air through a maze of apertures to the filter box. (I'm planning a ram air contraption) As you can see, there are a lot of extraneous hindrances to acheiving truck power levels via programming alone.

I'd like to add a mild quadzilla stealth module to my van, but it is my family ride, so the warranty must remain intact. On top of that, the EGTs run unbelievably hot just stock. I'm going to put an exhaust system on it soon in hopes of lowering the EGTs.

Now I am going to blow your mind:

For reasons I would have difficulty clarifying, my van feels plenty spunky just as it is. It tows with much greater ability than I ever could have predicted by looking at the numbers. It may be the VVT, or the torqueshift, or programming - I just don't know. It "feels" quick, it passes well, it tows well.

A Quadzilla would be added primarily for the fuel economy gains produced by advancing the timing.

My torqueshift has the overdrive off button only.
