408 on the dyno friday

[maze2525]

so a MS4 in a 408?

im betting torque is around 415-422

your numbers are about right for that combo,enjoy your combo

Yes you are correct. The tq was 424, but still can't understand why its throwing a code one time at 6200 then the next time its not. And yes its still the 5.3 maf who makes a bigger one? Im not getting enough air threw it for the top end
