Alo. I just put a FWI in my '02 GP GT. I used my own ideas(stock rubber pipe that comes off intake cut to correct angle, a 4" stainless steel pipe cut to approx 16", and a spectre 4"x7" cone cotton filter). I cleaned my air flow sensor with brake clean and blew it off with compressed air and made sure everything was spotless prior to final installation. She idles fine and runs fine during normal acceleration. The problem is when I get the gas peddal to about halfway and beyond. It still makes the amount of noise the engine usually does but it's acting like it's not getting enough fuel for how much air is being sucked?? Pretty much it accelerates fine up until 50% throttle but after that it make lots of noise but almost seems to bog down with 80-90% throttle. This is the first only mod I have done. Also anyone know if I can cut my cat and downpipe completely out and replace it with a straight pipe without messing a bunch of sensors up? I would probably reinstall the o2 sensor into the straightpipe.
