Good fuel pressure to start with to idle 550s?
I just got done with my turbo install, and I doublechecked everything and went to start it up. First few minutes, it seemed to run fine, idle was around 1500-2k before it warmed up. After warming up, idle dropped to around 500-800 and it began to struggle a bit. If I gave it some gas, it would rev up, and then stall out after I let go of the throttle. I tried turning the idle up via the adjusting screw on the throttle body, but that didn't seem to do anything. I also went from 35psi fuel pressure(vac on) to 45psi, and that didn't seem to help either. I'm running Hondata S200b, RC saturated 550s, Walbro 255lph hp, NGK racing 7 heat range plugs, and a basemap I got from Lightning Motorsports(where I got the Hondata). Really need to get my car running decent enough to be ready for a streettune with Mase tomorrow. Any help is greatly appreciated.

As a last ditch effort, you can tigthen up the throttle cable to where it revs a little higher and be able to idle.... then you can get it tuned and it'll idle perfect at stock fuel pressure.

I just took the car to get some gas(down the street, maybe 1/2mi round trip), and it felt pretty sluggish. I would have to rev it way higher than I normally do to get moving from a stop, and any sudden throttle movements would make it sputter pretty badly. Getting to the gas station wasn't too bad, but on the way back it was a different story. The car almost shut off 3 times, and one was pulling out into traffic. My pos narrowband A/F meter reads all the way lean at idle and doesn't bounce around like it normally does until i give it some throttle. I thought there may be a vac leak somewhere, but the boost gauge shows 20-22 in of vac until the engine starts to idle funny. I'm hoping this is an issue with the basemap, and that it can be remedied with tuning.
