I am struggling with a 90 ZR1 not passing the NO since The California EPA lowered the limits to 541 at 15 MPH and 498 at 25 MPH sometime in 2010.

The car has only 50K on it and nothing has been modified. I did replace the Injectors with Bosch II design from Fuel Injector Connection in 2008 and that made it a much better running car, and it still tests the same as it has for the last 5 years, but it will not meet the new standards.

Since you passed recently, do you know what standard your car was held to? The old standard was 772 at 15 MPH and 711 at 25 MPH.

It seems a lot of 90 and 91 ZR1 owners are having trouble meeting this new standard.

If I can get enough feedback I will look into filing a request for reconsideration of the limit with the state EPA.
