My car has the shifts in fuel trims at 5000 rpm with every tune I flashed (including stock http://datazap.me/u/tor/stock-a00g-m...7&zoom=517-651 ).

Is it worth (and possible) getting rid of? I suppose that has to do with the injectors?

Injector scaling and the PI/DI ratio will have an effect in conjunction with your maf scale. Temperatures, fuel quality, and perhaps elevation will also have an effect where your fuel trims end up. Since the latter 3 is continuously variable, I think its best to just to dial your MAF scale under "average" conditions (eg intake air/engine operating temps, elevation etc.) for the least amount of LTFT and call it a day.

Other things you could do is try to match the PI scale to DI as close as you can, dial the MAF IAT compensation table, and change the CL switchover point to where the fuel trims are the most stable on your particular tune. Though, that is a shit ton of work for very little improvement in performance.

Again, it's probably best/safest to dial your maf scale and OL fuel table to where your car runs on target to slightly richer than target with least amount of fuel trims (+LTFT's) on average and call it a day. You much rather have it running too rich than too lean.
