Increasing E30 gas mileage

I'm getting 20.2 around town; highway used to be 24.something but haven't done any road trips lately.

Plugs, filter, plug wires (performance set from BavAuto) are all less than 1 year old. Distributor cap is new.

There was a thread on using 19 lb injectors to increase mileage somewhere but I've also read that that tip is bunk.

Thoughts appreciated...

That sounds like a 325i running normally. And yeah, the 19 lb injector idea is bunk. Watching the MPG gage can help a lot.

Bav auto plug wires are garbage....maybe it was just my set, but I got rid of those after a week.

yeah ditch the injectors, go back to a set of rebuilt and flowmatched stock injectors...

also try cleaning out the AFM for some MAF cleaner in case its sticking, that helps supposedly, i am yet to do this

O2 sensor going out, a replacement might help.

O2 sensor is 3 years old; should be working fine.

Well other than some induction mods looks like I'll close this potential project.
