Can I delete emissions but keep air pump for cat?
I'm cleaning up my engine and would like to delete as much as possible and be able to maintain sequential and keeping the cat.

I passed using a electric air pump and a pulse modulator to controll pump speed. . Saturn cars come factory with a electric emissions pump. Very easy to install and doesn't get in the way like the factory pump.

Yes I have done it as non-seq and then with a single turbo.
But I used a PFC ecu and a lean map for the tests.
Running some ethanol or e-85 mix to lean out the fuel helps redcue hydrocarbons.

If you're deleting emissions, consider removing AWS and double-throttle too.
