have datascan and your laptop in the front seat go to a place you know and see if you can have them hook it up just to see your levels go into active test on datascan retard your timing a littlebit and take away some fuel and see if you can get it within range. if you can write down what you did in active test to get it to pass and have them smog the car this is what I did last year my car has dp's tp's no egr 740cc injectors and i passed worth a try
