[Im JDM Yo]

I realize its just an AFC, but after im done setting up my car, should i take it somewhere and have them tune it?

Problem is, one of my injectors is dead, and im getting 550's out of my buddy's supra for free, so what better time then now to put em in. Now i have to buy an AFC to calm those bitches down... And im making sure leaning it out a tad so i dont run super rich wont hurt my motor.
