Message Looking at your sheet, you got a NA on the Ignition Timing.. They do not check it??

Thinking I'm remembering something about retard the timing to 5 Deg BTDC. that will reduce the burn rate.. drop the burn temps temps and lower the NOx.. should bring up the HC's but you have new cats, and they are doing a good job now..

Also on the sheet, is 'Modified'.. for other emission .. will that pass with a Modified on there?.. Does the Smog Tech know about the EGR?..
