pfc install, bad idle, lean idle,low vacuum???

[1997silvia]

i have a s13sr, mostly stock with gt28rs ,sti 550's, and pfc d jetro, just started it up today and my wideband says its really lean at idle and it has no throttle response, 18.0-21.0 at idle, vacuum is a about 13 inches which i always had 18-20 and it will idle for a bit and then jsut stumble out? i beleive that eveything is hooked up right, i am using the pfc boost add on kit so it is on if the smiley looking symbol means on ? i have a steve shadows tune in it, i entered everything he sent so that shouldnt be the issue. checked and rechecked everything for vac leaks and reassembled it all and no change. any help is greatly appreciated!!!

any power fc gurus please help!!! i did all of the initializing and resetting of the ecu, then i entered all of the tune components via the commander (which i will never do again) took forever.. so i dont want to start it all over again took about 3 hours to enter all of the values for inj and ign.

the map is plugged in
mafs disconnected
iat wired up and in cold pipe

help please
thanks

is your email something like "blackvtec" or something?

If so I think we alredy addressed the issue. You need to set your base correction for injection to 100%, not 60%, if you're using 370CC inj.

they are not stock injectors, i switched them with yellow sti 550's i am thinking that i may have at least one bad one and may buy new ones, yes that is my email and i did email you again this morning with a lot more new information

UPDATE!
so we got the car to idle good on 80% inj duty and drive pretty decent, i believe that i have a vac leak because of a bad wastegate, i ordered a new one just now, we pulled the plugs which are hks iridiums, they look ok but they may be gapped a bit high two were 30 and two were 32 thousands, i am going to put new ngk bkr7e's in it gapped at 28 thous or lower as i beleive i am blowing spark out after 4500 rpm, that was with anything over 15 psi, i lovered it to 12-13 and it was much better but not perfect, a/f numbers were a little rich under full boost at about 10.5-10.9 but still tweaking.

i am using the pfc boost control kit which seems to be working wonderfully.

timing from steves map seems to be good

still a little worried about the breaking up after 4500 rpms , i am hoping that new plugs gapped down will clear that up. then i may just have to modify the fuel map to keep it idling on 80% duty but lean it out to low 11 a/f under full boost?

comments and suggestions greatly appreciated

I think it's best if you address this directly with me over email

I think I can probably help you the most - send me these updates directly to me via email or PM, because I can't constantly be checking this thread.

I think you have an issue with the injectors themselves. If they are true 550CC injectors than you should not have to skew them only 80% correction, they would need AT LEAST 60% skew off the base PFC setup.

I have also sent you a few more maps to try out FREE of charge. Save the ones I already sent but try these out as well. I still think I would buy some denso or Nismo High Impedence injectors that you know for a fact are the correct fit for the car.

cheers
