ok... here's a dumb question... does installing a larger exhaust from the turbo back help to reduce back pressure and possibly make the exhaust backpressure code go away...? i ONLY get that code when i am running very high boost pressure at high rpm.... just wondering...

The easiest way to cure it is to run less fuel....assuming that is not an option

, the next most effective way is to install a larger turbine housing. That is assuming that you want to control the actual pressure and not just defeat the SES light.

You're right cookie, less fuel is not an option.

A turbine housing would be preferred, but $30 to defeat the SES light is a lot easier to swallow than $500 for a housing. A housing is still in the works for me though.
