[QUOTE="pooter, post: 945401, member: 7579"] so I just got my truck back from getting a new short block from the ford dealer . I had the tech install rcd egr delete 6.0 manis dark horse up pipes Midwest diesel stage 2 ported intake and a rcd 72 mm atmo . My question is on the stock setting of the performance tune of my mini max the boost is 32psi and my backpressure is 72 psi and my big tune my boost is 45psi and my backpressure is 72psi. Does my back pressure seem to high? I also have a sb cai on the truck to and it still has the stock cold side pipe also [/QUOTE]
