OK, I live on the dark as I have an old Ford IDI 6.9. My brother however has an 08 Duramax and wants to find the best programmer for his truck.

He has the Edge off road only programmer. It is messing with his turbo at lower rpms and his economy has dropped off to 12 mpg or so empty.

He has is straight piped and has removed the particulate filter. He also has all that cold air intake stuff on it.

0-60 in 4.6 seconds in 4 wheel drive and spiking EGT's. He is going to kill the thing.

Now he wants to find a programmer that will give him the best economy on a low setting and all the safe power his truck will take.

Anyone have any input on all this?
