[QUOTE="sonic blue l, post: 323741, member: 5185"] Yeah I just drilled out the orfice, left it smaller then the fuel ports vs a 09 rail, but closer to matching the size of the 08 injector ports. I only did it because I had the truck a part and was not sure of future plans I may have for it. At the time when I google it, I didn't find anyone with issues. Considering the orfice is less then a 1/16" i was surprised how much power a 6.4 can make. One could see how injector demand could cause a loss of rail pressure. I've had no drive ability issues, however I wonder if the rails people buy are hogged out more. Those with the issue can you explain exactly how you get your truck to do it as so far I've driven in town, on hi way with no issues. With that said I'm currently doing an oil cooler and a few other odds and ends I can try to duplicate your issue. My truck however is pretty much stock except for egr block off plates, removed throttle plate, ported intake elbo (removed egr feed tube restriction) [/QUOTE]
