If I swap out the bearings and get the blower ported it will pick up horsepower

Can the pcm compensate for the added hp with fuel or I need a tune?

Depends on who you talk to.

Some will say you're fine.

Others will say that the fuel on our cars is already maxed out, so adding any increased demand on the injectors is asking for trouble...

The problem that was seen on two cars on this forum last fall was injector duty cycle hitting 98+ percent both stock cars. Cat over temp kicked in causing the computer to dump more fuel. Fuel pressure went down and the stock fueling in the car just couldn't keep up. DA was around 0 the day @vortecd logged this on his car.
@moparjim was the other and he put a tune on his car adding no timing but fixed the Cat over temp issue and picked up a couple tenths.
