I am fairly new to the Duramax world, but have quite a few hours of reading on here. From my research on here it appears that the V2 is for data logging and retrieving the stock programming for use by a tuner. So, I'm thinking that I need to purchase EFI live first and use the V2 to upload my stock configuration to use by a tuner to make my new custom tunes? Also, I have heard that some distributors rent V2's for this or do I have to buy it? The reason I was thinking I needed to do this is because I need the tunes to load after doing my exhaust (DPF delete), EGR delete, and PCV reroute to keep from throwing codes.

Thanks

Some rent them, other do a PCM swap (they send you one, and then you mail yours back).

I prefer having a V2, it is a truly invaluable tool that can diagnose many issues. It isn't necassary in most cases. But alot easier if you have alot of mods planned in the future.

It is all up to End user and your needs.

Might check out our new SPADE option. It is EFI Live in its simpliest and cost effective platform. It does cost a bit more than a Pretuned ECM, however you keep it and can read and clear codes as well as data log.

So, I DO need the V2 (rented or own) to get my stock tunes and send to a tuner then before I can do the other upgrades unless I want lots codes thrown???

With the SPADE all we need is your VIN number we then build your custom tunes and load them onto the SPADE unit and ship it your way.

If I want to use EFI do I need V2 or to rent it in order to get my stock config?
