[QUOTE="weekendwarriorfsw32, post: 698092, member: 771"] Been comparing specs from my 6.4L auto to my buddies 6.4L manual transmission and for some reason he seems to be running higher BP. Pulling a hill with 10k he is seeing 60 psi BP and 42 psi boost running Spartan 210 with an Elite atmosphere. When he gets on it he is seeing up to 72psi in that same tune. Any chance it is because of the transmission? Even taking off normal through the gears it is getting up to 50 psi back pressure. I am always at least 10-15 psi less than him with the same set up. Thoughts? [/QUOTE]
