So I bought a Hot +2 ET from a guy who said he never installed it, it was brand new. That's not the problem, I'm looking up the tuner on PPE's website cause I was told it wouldn't do DPF delete and according to the website it's for a 01-07 model year (1110400), the (1110500) is for 07.5-10. Now the one that I have says on the sticker on the tuner 01-10 and the instructions list the LMM. So what's the difference? Will it work on my truck? If not, what do I need to do? Dan?
