So my h22a1 in my 4th gen has a built top end and has had a crappy street ECTUNE tune for a year now. Im a broke college student so dont tell me to go to a different tuner please. Its so crappy it will run side by side with a stock vtec lude . I ran injector cleaner through it the other week for ***** and giggles and now when I'm on the gass I get even more black powdery soot shooting out my exhaust. Is it in my head or is the car runing significantly richer now that I cleaned the injectors? It pops now when I downshift through 4th and 3rd...
