Could be quite a few things, did they replace spark plugs? If the gap is too wide you can get that type of hesitation even with zero knock. Another thing might be a boost leak of some sort, check all your hose clamps and make sure the everything looks good underhood. The stock flash from Mitsu, even the latest, is still way rich with high timing so likely a good tune for 11.0-11.5 AFR's along with appropriate timing and increased boost will clean up the rotten factory tune.
