91 egr
Hello, i’m new to the forums and i am planning on building my c4 into a track car.
So.. I was planning on doing an egr and smog pump delete and couldn’t seem to find a kit online for it. I did find one for the 87-88 350 TPI and was wondering if it would work?
The other part of this post, does anyone have recommendations for the first performance upgrades i should invest in? Thanks.

I think the air pump serpentine brackets are different. Www.tunedperformance.org for tuning and hawks has just the egr plates

The calibration has a 100mV offset on the O2 voltage when the AIR is on (due to the extra O2 it puts in the exhaust so the ECM doesn't think you're running lean).
So you may get a slight rich condition when the ECM thinks the AIR is on but there's no added O2 in the exhaust anymore.
the correct way to do the deletions would be to go into the calibration and disable them too.
