I had a 22re in a Celica GT-S with a stock rebuild and no mods other than balancing. The result was very noticeable and i will always spend the money for performance balancing in the future.

I had a 20r with a TRD adjustable cam gear and no other mods and stock cam advanced about 5* made it a lot zippier in lower rpm’s

I have done EGR delete per the old TRD white paper method, which is placing a BB in the vacuum line to prevent the EGR valve from opening but keeps everything stock appearing under the hood. This yields better throttle response but no improvement in gas mileage.

I have had the injectors cleaned on my current 22re and received a flow report before/after. None were terrible to start, but some were better than others. End result: afterward, each cylinder probably contributed more equally to power production, but no improvement in gas mileage.
