Programer ?

[farmboy99]

My friend has an 03 duramax, what programer is the best one to use on the duramax? Hes looking to get about 400 to the ground, can just the programer do that? im used to the 7.3 where you get about 300 max on just a chip... lol

I imagine with EFI Live you could get 400 fairly easily....but I'm not a Duramax guy.
