Don't you have to get the ECU re-mapped or piggyback it to tune turbo, both which alter OEM specs?

Is passing emissions with turbo even possible?

 

Its possible if its tuned, why is the STI able to pass No seriously though, if you get it tuned and map properly, there should be no reason it wouldn't pass. Unless you live in Cali or something.

 

I passed.

 

What type of engine management are you guys running? Internals? How long/how much did it take to tune?

 

on a good tune you can pass, and you should be able to clear your cel's with EM

 

A good tune and plenty of denatured alcohol.

 

my car was fully tuned for $300 on a dynapack

 

No emissions here, FTW

 

If its anything like AZ you have an idle test, and a loaded cruise test, neither of which put the car into boost, so passing emmisions is pretty simple with a turbo. Any decent tune on a car will get you through.

 

it depends, do you plan on passing with or without the cat? and regardless of emissions, you should never boost without tuning and a means of tuning such as a piggy back or ecu.

 

is it possible in california to pass smog
