Also check the setting (forgot what it is called) which switches over to PE mode. When I put the 3.25" pulley on the old 4.8 there was a range where I was getting boost while still in 14.7 AFR closed loop mode. Not the best situation. There are 2 settings: MAP and % throttle. I believe I had to lower the % throttle value.
