I had a custom chip burned for my car to get it up and running. I am running an ebl p4 for my 383 tpi with a procharger d1sc. I noticed after getting everything dialed in closer that the egr was disabled in the burn for the prom. Would it be worth me adding it back into the tune or should I leave it disabled? I know this is always widely debated, but I am looking for advice from someone who has a lot of experience in prom tuning wether there would be any benefits or not. I am still new to the whole tuning thing. Thanks.

 

Do you need to have emissions checked where you are? If not, then there is no reason to enable it. As for the tuning benefits, I can't say one way or the other. Might want to to move that question over to the EFI/DIY Tuning section.

 

No emissions testing done where I live. I just wasn't sure if it could possibly help with reducing detonation at all.
