Got the car running.. Needing some tuning I think..

I set the base timing around 7 degrees and it jumps to around 20 w/the EST wire hooked up.

Running 30lb Inj's and it smells pig rich so I am sure I will need to get a chip made..

Anybody else encounter this---I removed EGR provisions and 9th injector completely and I am YET to get a SES light?? What is up w/that?
I still think I am going to have Ed Wright make me a chip.... More to come!!

Re: MR Status

Ran it tonight.. pulls REALLY nice up top... It just kept climbing at 6k and I figured better let off...
I got a '33 and 42' code tonight.. MAF is due to too much airflow at low rpm's and 42 I am not sure... Says the HEI unit per my book?? Anybody??

Sounds like its time for speed density with that setup. The MAF is being totally overwhelmed by it. Also, with the 30's, you need to scale back the injector constant to match. That will clear up the fueling.
