OK, here's the problem. Even warm, my car is idling at 2K.

There's the setup:

d16z6
t3 turbo
missing link
dsm bov
audi 5000 intercooler
stock injectors
msd inline fuel pump
B&M adjustable FPR
Vortech 12:1 FMU
stock p28
and other junk that shouldn't affect this at all...

Yes, this is a temporary setup, until I can afford a hondata. It's going into storage very soon, and won't be run other than starting it a few times a month. Before doing any modifications to the fuel system other than the FMU, it was idling fine, and out of nowhere went nuts. Added the fpr and pump because it was leaning out in the higher rpms. It's not throwing any codes, runs great other than that. I've gone over vaccum lines a million times, and can't find anything... Any help would kick ass.

 

Check your intake manifold gasket, did you put a new one on when you built this? what I see happen is, add a turbo the intake is now pressurized, an old gasket cracks and leaks, idle high or surges. Also, since this is not a kit, if your blow off valve just dumps under the hood, try hooking it up to the air intake tube, yeah I know it wont sound cool but see if this cures it.
