Which TC VDF for 2004 Cadillac Escalade 6.0

[Team ZR-1]

As in the title which TC VDF ?

Have to fix one that has a supercharger and owner was not wise on this and allowed a dealer to flash the PCM to update it and lost the tune

Thanks.

BTW a funny one, customer has a 2005 Silverado 4x4 with a Whipple supercharger 6 liter engine.
Owner has been driving the truck for over 1 year with it on.
Comes to me for truck in hot weather has lots of knock.

Put scanner on it and we go for a drive for me to see engine HP is less then what would be stock even when boost would be on.

Start checking all the wiring for the Whipple controller that also controls a boost a pump. popoff and 2 extra fuel injectors to find it was never wired correctly and the pop off valve never commanded to close

Thus all that time engine was pulling the Whipple doing nothing.
Contacting Whipple they told the owner to take a hike as they no longer support that model so I ripped off their controller and injectors, installed larger injectors and tuned.

Output increased 150 HP and 100 ft/lbs Tq and fuel mileage went up

Owner goes for a testrun and comes back laughing that he never knew engine was not getting any boost.

Ifr you have the cal or bin and try to open it, it should tell you which VDF you need or if you know the OS you can look in the PCM.DAT file and see which one is listed on the line with that OS
