Diesel Chip for 06 E-350

[HAB]

Which is the best Diesel Chip for 06 E-350 Cargo VAN
used for towing RV? All I find are for Trucks.

I have an E450 with the 7.3L PS. I stopped at a local truck shop and asked this very question. The shop owner said he had never seen a chip for a van with a PS. When I asked why, he said the vans don't sell enough PSs units to make it worth while to the chip makers to do all the testing and evaluation. He said since the van engine was detuned (all the vans have less HP that the same year truck engine) it was a totally different chip that would be needed than in the truck.
