The TRQ curve dictates when enrichment is needed. Please to do not listen to hacks telling you to zero all these tables and settings. If you do, You end up with poor mileage and lots of carbon build up in the motor from the over enrichment as you drive around town. Gas is expensive. There is no excuse to just waste it

Can you explain a little further? Is the EPA forcing Subaru to run a lean tune from 3-4k? I'm assuming it's the same in the WRX, but not a problem because it runs lower boost and TQ?
