I have a 5.0 mpi with the 1.47 ratio in my Tahoe and I am trying different props as well. Here is what I have gotten so far. RPM's are from the factory tach. I also ran the numbers using the prop. calculator and came with a preferred pitch of 17 but due to the performance I am not convinced. Possibly a different style of propeller is needed.

I should try the 14.25 instead. Maybe a custom prop. is the answer. I will keep trying and let you know.
