If you can, put your screen back in your MAF or get used ends.
The main way to adjust your fuel Ltrims is to adjust your Injector Fuel Rate table. You scale the whole table by a %. For example If your Ltrims are around +7 when cruising, then multiple the whole table by at least 93%. By doing this, you allow more fuel into the engine.
After you get about 20-30 miles on it, make sure your Ltrims lock at 0 when your at WOT, then your ready for the dyno.
Do this before you get on the dyno to do WOT tuning.
