2.7L Toyota 2TR-FE engine poor mpg. No lights . What can i check ?

Hi guys i have a tacoma with v4 2.7L engine 2TR-FE
No lights , but. Getting bad mpg and sometimes loss of power. Old owner did bore out the first catalytic converter and i think the 2nd one right behind it is semi bored out. Thats what a mechanic told me when he took out the whole setup. He said it wont cause power loss if anything itll give more power but louder , which it is much louder. But im worried about the mpgs. I did notice tires little low like 30psi would that cause bad mpgs ?

I'm game! What's a 2.7L V4, a 4.0 with two spark plugs pulled?

You need an air fuel ratio tune. Anytime you modify the way the truck breathes and exhales. Yes you will have more power and torque after proper tune. Before you do that I would just remover the cats completely and straight pipe them.
