Anyone tune one with efi yet?
so far the only company ive seen do it is h&s
If you don't want efi and having to use a lap top or efi is to busy with Cummins stuff and you dont want to wait then PPE is the next best option. Always has been for the Duramax's so I'm sure when they come out with theirs it will be good stuff.
Bump, any more interesting news?
