whats up Ht jw i just did my gsr swap but i kept it obd0.will a pm6 ecu be ok for the mean time while i break the motor in.

stock except for skunk2 manifold,edelebrock throttle body,je pistons and ls crank and rods..i believe my compression is 10.72 according to a compression calculator.

 

break it in on the dyno then proceed to tune it right away. that should be the only breaking in it needs.

 

so there's no need to break it in to 1000 miles and do a oil change every 200 miles?
