2006 RSX Type-S Bad MPG

In my 06 Type-S I’m hitting the gas light at around 220 miles on a full tank while driving economically. I’m posting the list of mods I have on the car that I think would affect MPG and I just wanted your guy’s input on why it might be so crappy. My assumption is that it’s my AEM Short Ram Intake but I’m not sure. Swapped out the spark plugs as well recently.

AEM Short Ram Intake
Injen Exhaust System
CE28 17” Wheels
235/45R17 Tires
Stock ECU

Does your scan tool show live data? Can you drive normally and pay attention to the short term and long term fuel trim? what is the average values? It should be close to -5 to + 5. Post the values at idle and while driving on a flat road while going a normal consistant speed. Also, look at the engine coolant temperature and make sure it's at 180+ degrees F while the engine is warmed up.
