Do you have any modifications on your car? There are multiple reasons why your car could be running on a lean condition. Do you have a check engine light on?

Get the code read from your check engine light if you already have not and post what the code read. Also after your PI swap you should have a tuner with a custom canned tune or custom dyno tune after you do the swap.
