Let me know who their tuner is. And is their dyno in that shop ? I have been there before and didn't notice their dynos. Jeremy told me they have a dynojet and a mustang .. let me know ... and interested how good is their tuner . I just need to dyno my 6 speed stroker to confirm the figures given to me by the past owner and past dyno sheets and eventually in the future get my SC tuned ..
there are two black supras and two white SCs there right now that belong to good people I know .. and I believe the black or dark green SC of iridebmx is still there for repair too.

The tuning will not be done at Zen Motors, it wil be done at Lethal Injection or the other close by shop named ???? Performance. The tuner they are using is a guy they know and depend on with all their builds. Jeremy says he travels all over. I will know exactly who it is tomorrow when I meet them face to face. I dropped it off at Zen's to chnage the oil, let them look over everything and make sure it is all good, and change the wastegate with a larger spring..

I saw one of the white supras, and the 2JZGTE is out of it... Rebuilding the bottom end, it belongs to Jay. The other green one belongs to Devon, a buddy of mine. He is the one that I actual bought some stuff for my build. I saw a MKIV in black in the back part. Didnt know anything about that. Their shop is very busy right now. Saw a total of four of them in there.

Doomlight answered it correctly. Bypassed the fuel pump ecu completely. Used a seperate relay and triggered by ground by the AEM.
As for the dyno it is on hold. It has been here since 830, and they have been troubkeshooting the injector wiring. They retuned all the maps and started surging again. Still troubleshooting why it starts out rich then real lean with such a small adjustment on the AEM. I didnt think it would be like this since I have driven it so much. I will be leaving tuned or no tuned tomorrow regardless. As of right now it has been a wasted trip and I am totally disgusted right now with it. I wish I would have been posting videos instead of this sob story. Will update as it goes here.

So what you have a fuel pressure issue?
what pump do you have in the tank?
what's your BPF?
How much is the FP dropping?
How old is your fuel filter?
Are you sure the sock on the fuel pump intank is not clogged up?
Are the injectors brand new? If used did you have them flow tested?
Can you borrow a FPR maybe yours is faulty?

the fuel ressure is good, changed the coil packs, new plugs, and ignitor, still surging. Everytime we lean the idle out is surges more. Its driving everyone crazy. They are leaning toward the wiring of the harness.. Guys I need some help here.. I didnt have the injectors flow tested, due to them not being in the car very long. Maybe I should have.
