If the car still has a MAF, there is no reason they should have had to add fuel, unless they fixed something else or the old tune was screwed up. The MAF will compensate for a more airflow like a bigger turbo. You can usually put cams into an Evo and the A/Fs will be pretty much exactly the same even if it gains 40whp.
