I think you could prolly improve your power and gas mileage by getting rid of those TII injectors. Just me? Get some N/A injectors and get an SAFC2 to lean out the mixture in the midrange.

Putting a cat in would not help your gas mileage at all. Do you know how one works?
You do not need those TII injectors. Trust me. The N/A fuel system is supposed to support up to 250hp. You don't need more fuel going into the combustion chambers.

Haven't we ALL heard this
Yeah, get rid of those TII injectors and put what came with the car back in there.
Your NA should get at least 25mpg on the highway and 20 in the city. Did you put the oxygen sensor back in the exhaust after you had all that work done on the exhaust?

Like everyone says, the turbo fuel injectors are HURTING your fuel economy.
