Still Confused

hi all,

i have an r33 gtst rb25det it is standard except for boost gauge and $22 boost controller and 3' exhaust high flow cat an cannon.

every morning for the last 2 weeks now it has coughed and splattered on initial first turning over in the morning for the first few seconds the as though it gets rid of some shit fuel in the line or something ,kicks over and warms up to gain comfortable idle. i only have the boost controller turned to around 6psi on my gauge as i don't have a powerfc yet, i have read shitloads bout "rich and retard" so don't need to waste excess fuel at the price it is. when i do press it it does have a hic up or 2 if i don't ease on accelerator as boost and rpm are climbing.

i have the boost gauge air line t-peiced in the vacuum line running from the plenum to the throttle body i think it is??? could this be a problem and is the boost gauge air line t-peiced in the right area?? if not where should i tap in to the vacuum line???

thanks

thought either that or maybe injectors, coilpacks just no sure.

just put some nulon fuel system cleaner through it, is this a good thing or bad ??
