will an itr with jun 3 cams pass smog with a full stock exhaust system? valve cover is not cut either.

 

I would say it would depend moreso on the tuning. If it is a real rich fuel map, you will probably have problems.

You can always throw the stock ECU back in (or revert all changes to zero) and go in there with a stock fuel map...just make sure you change them back before hitting the throttle a lot.

 

With the way your running now, no.

 

a full stock exhaust system is not gonna help you pass smog

 

wont using higher octane(100) help as well?

 

I dont think so. I think the JUN ecu is set to run rich (or atleast mine is). If you have a VAFC you could try to lean it out.

 

put your stock ecu back on...oh wait, nevermind

 

doh..leme borrow yours
