Duramin Express

It’s detuned 115hp/200lb-ft from the truck LMM via PCM tuning. I have addressed that and gone a fair bit further with the tune. Theres still more left if he wants to push it! As far as the EGR block-off goes, I’m not saying it will add power by just putting it on. What it does to is allow you to add more boost pressure without having to worry about the EGR valve blowing open (it happens, read up). Obviously the valve CAN still open, it just wont effect it any longer.
