ser gtr will figure out how to reduce idle by blocking vaccum on itb, vaccumm when not in place send wrong signal to ecu. he knows where to get information. he has my number also, in case you feel like talking to me
my setup is taking vaccumm frm 4rth throttle only instead of intake throttle cover air pressure. i have a aluminum made adaptor for tilted itb with vaccumm pipe slot built -in
it has interesting first start of the day on cold engine, lot of backfire:).
yes i found importing T T Tuning parts much easier than dealing with people in pk.,
