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.

 

well i figure common sense is that catlytic converters reburn gas....i figure that might help then doing a major change like that....those injectors help me...lol

 

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.

 

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?

You need to read up on how all these things affect each other.
Like everyone says, the turbo fuel injectors are HURTING your fuel economy.

gotta love injecting 17% more fuel than the ECU thinks you are... does WONDERS for fuel economy!

 

yea the o2 sensor is in....and i didnt switch the injectors the car came like this and the reason from what i was tld that the n/a injectors were leaking or sumething so thats what they did....anyways....i appreciate it guys thanks....guna look into it
