Sr20det won't run

[flyinryanp]

Ok here we go. Have a sr in miAta wiring specialties harness Jim wolf Ecu
Greddy knock off manifold, top feed injectors but basically stock.
Car will start idles then bogs down will hardly run, mostly will die out
If I put my hand over the Maf I can keep it running at a decent idle.
Things I've check, Maf swapped two of both have same readings 1.9 v,
Checked cont. to Ecu. Set tps .45 v sweeps nicely, can't find any vacuum leaks
Been all over with propane. Checked bottom injector o rings with propane
And oil to see if it sucks it in no change. Check timing 1 million times and also
Counted teeth on cam gears that's good. Psi checked piping intercooler etc. fuel
Psi is set at 43 psi. Plugs gaped at .027 to .030. Swapped around coil packs no change. Car acts like it has huge vacuum leak but can't seem to figure anything
Out. I'm a certified mechanic never struggled with a car so much especially this
Simple I have to missing something stupid. Taking any and every idea.

What MAF are you running? If you unplug the MAF you have, will the car idle?

Also, check the ECU for any thrown codes.

Id confirm good spark, check injectors out, hook up a vacuum gauge and wideband
