... I posted on this awhile back. Got alot of responses... but no actual 2006 file.

I would like to know if ANYONE has an HP Tuners file that is a STOCK 2006 6.0/4L80E file.

Please email me at billreid1@***.net... and/or upload to the HP Tuners repository with notes that state transmission is a 4L80E.

Much Thanks,
Bill

 

I can get an EFILive Hummer H2 2006 6.0/4L80E, but I don't think that would do anything for you.

Any chance you could find a truck on a dealership lot to go "borrow" a tune from?

 

You got mail.... but its a 2000 it might help

 

If you still need the stock file pm me

 

I probably have an 06' on the lot I can get if you need.
