Question on new motor install and tuning.

hi gang.
quick question.

im getting ready to install a forged sb. same cubes. not really changing that much. just all forged. (pistons, rings, rods, crank

, full assy, fully prepped, but same cubes),

would i need a retune? or should i be good to go with my current pro tune?

I would think it would be pretty close if your running the same cubes and cam. You may need to adjust a little for the lower compression, but nut much unless you up the boost or shot of NOS

I'm going to run my new forged motor on the same tune and adjust form there...
