Ive been building my lb7 the last year and finally finished it and got to dyno. It put down 747hp and 1400 ft lbs at the wheels on fuel. Single gt4202r, single cp3 50% over industrial injectors. It was more or a less a break in tune, It dropped rail pressure to 19k on the dyno so i know it has more in it. I hauled 15k this weekend with it, pulled like a champ. Im veryhappy with the setup just thought id let yall know.

thanks

yes modded cp3. on the dyno it made 52 psi for a split second then fell to 38 when rail pressure dropped
