Who knows if a 1993 lt1 obd1 needs egr deleted in the ecm I’m building a 383 and don’t wanna run evap or egr but don’t want the egr in the computer to advance timing and eventually ruin the motor from temperatures that we thought didn’t need to be deleted out of the computer .I been told yes it does and well if it does who can tune my obd1 don’t say Solomon 1993 transam computer. email address or phone would be good so I can mail it to them I drive over the road so I don’t have a lot of time to be fooling with trying to get a computer and getting cables and figure it out what to do

thanks

Have you considered PCM of North Carolina:

https://www.pcmofnc.com/product/1986...-order-tuning/

You don't send him anything except a description of the engine and your requirements. He sends you a new chip.

 

Or you could do what I did and switch to a 94/5 pcm/harness with MAF and get away from that chip burning nonsense and your tune options greatly increase.
