Bought my first diesel 04 lb7 GMC 2500hd want to do straight pipe and do away with the codes from that. I'm not intending on modifying it a lot. It has air dog fuel filters and new lift pump already from what I was told. Got it for a good price. Just want to add a little more pep. I'm not looking for a hot rod. I do some pulling of tractors and such that's about it. Other than that it's a daily driver. I'm reading on this POE system what would be best fit for me?
