Hey guys can some one please help me, I installed a APEXI PFC and i added the base mod map to it, I started the car and did all the learn procedures and now im revving at 2000rpm. I did what Dale CLark said buy closing the bleed valve at the botton of the TB and open it up about 1/2, I did that and it drop from 2400rpm down to 2200rpm. I had to to close it more, its about 1/4 open and it got me down to 2000 even. Well my ? is there is a piping thats comming off the UIM near that fire wall and tps, Am i getting a vac leak from there, if so can i just put a cap on it? I have check all the couplelings and screws, i have check the solinode valves, and i cant find anything, so thats why im hear. so if you can share your knowlege please help thanks.
