Best Performance Chip for 6.0 Diesel E-350 ??
I have the SCT Live Wire, which comes with several programming options.
While I keep it on the TOW50 setting (50 hp more than the stock TRUCK program), I have played with the STREET program and it makes the van hustle. I think my reading was around 16-16.5 seconds at 91+ MPH in the 1/4 mile. This is from a 9000 lb van with a 3.55 rear.
All of the settings firm up the tranny shifts a little, too.
You can also get a custom program for your rig, which I've been telling myself to do for the past year or so...
