Looking for some source of tuning

I want to tune my s14 sr because its running off stock ecu. It runs good and is efficient on gas just reaks of fuel and puffs a diesel amount of black smoke when i rip it (not really lol) just looking to get the AFR’s at a good reading to crank out some more power with some supporting mods

used standalone (or new) AFC power FC whatever the **** you have jus interested in a price product ad condiiton, text is IDEAL, PM’s will be delayed
