First heres a mod list:
This cylinder head was disassembled, cleaned, inspected, and reassembled with the following components:
-competition 3 angle valve job with 0.040" valve seats
-Valve job performed on a Serdi machine
-cylinder head ported and flow tested on a SuperFlow 600 flow bench using Audie Technology digital interface
-exhaust valve guides replaced with manganese bronze and honed to spec
-all 16 valves reground using Kwikway valve grinding machine
-cylinder head deck milled to ensure flatness(0.010" deckmill)
-valve shims ground to fit Tomei solid lifters
-fwd sr20de valve cover powder-coated black with breather baffles removed and rear breather tube plugged off

-HKS 272 step 3 intake camshaft(228 degrees at 0.050" lift, 12.6mm lift)
-Nismo 280 exhaust camshaft(224 degrees at 0.050" lift, 12.6mm lift), this is an extremely rare camshaft. it was briefly made and I had to buy it directly from a distributor in Japan.
-FWD Cometic 0.040" MLS head gasket
-Nissan Pulsar GTI-R individual throttle bodies
-Cutsom made intake plenum
-Profab insulating intake manifold spacer gasket
-Nissan Pulsar GTI-R 444cc injectors

-MAF replaced with MAP sensor
-Tuned with AEM Series 2 stand alone
-Stock bottom end
-We are using all of the factory sensors, harness, and ignition components from the sr20de

The car is at the garage now and has been tuned already as of Tuesday. Now the car put down 119whp and 105lb torque which honestly I'm kinda embarrassed about haha (this car NEEDS boost.. I know) but first we need to work out an issue the car is idling at 5000rpm and the ITB's are adjusted all the way down so I was hoping you guys could give me some ideas on how to resolve this issue. BTW we already checked for vac leaks and there aren't any that was my first guess. I know I have to sync the throttle bodies I ordered the tool just waiting on it to come in the mail, but I doubt them being out of sync is going to make the car rev to 5000rpm that's almost wide open. I also read in a different thread that people used vac blocks in there setups but im not sure exactly how these work so if any body has experience with these please share your wisdom. Any and all input is appreciated you guys have been awesome helping me resolve issues in the past so I'm hoping you'll come through for me again.
Thanks, Anthony

How is the idle setup with you're itbs? I've seen some run a custom iacv tapped into each runner and I've seen some crack three throttle bodies just a hair for idle. Either way your letting in way to much air.
