i have an 01 formula with 86k. mods are slp cold air intake, smooth bellow, nkg plugs, msd wires, lpp long tubes, ory no cats, slp loudmouth catback. and i purchased a pcm from bryan at pcmforless. i noticed a hesitation between 2-3000 rpm but not consistent. sometimes it puts you back in the seat other times hesitates. i replaced fuel filter. seemed very clean. checked fuel pressure at rail 55 while idling, 60 when revved up. but i am not capable of checking it under a load. only when sitting there. but it always revs fine with no load. i can smell fuel when idling but the plugs seemed lean. (whitish in color) i also changed coils. the problem was there before any mods. but started shortly after driving it. with mods seems more noticeable. only diagnostic i have is an obd2 and the car is throwing no codes. ANY help would be great this is driving me crazy i just want to get it figured out before i put it away for winter.

try ohm testing your injectors, sounds like 1 may be on its way out.
