Terminator won´t run

Hey guys so here is the Story.
Got my car tuned, drove it for 80miles or so, 1 trip to work, back home, washed the car´, did a 3rd gear pull on the freeway, cruised 15 more miles. Stopped for a drink and the car considered to not start again.
So looked at a few Things and car will only start under WOT but no idle at all, returned the tune to stock and could drive home, idle was fine.
After that i pulled the hose of the frps, no gas at all, unplugged the connector and car runs with the tune on.
So yesterday i changed the frps, car runs like crap is fully rich and dies every now and then, smokes black.
Again returned tune to stock, car runs and drives afr goes to normal readings.
FRPS and TPS is new, IAC has been cleaned before the tune.
Mods are
dual fpdm. aem 320 pumps, ported eaton, jlt cai, 78lb injectors, catless h pipe, cat back, 2.8 upper, 2lb lower.

hope you guys will hav an idea
th in advance

Are you sure you're not backwards on your tunes? Your car shouldn't idle fine with a stock tune and 78lb injectors. It should be way rich. Even with the STFT's working.

Keep an eye on those pumps. They don't like to be run in a returnless set up. I learned that the hard way.

Sounds like an over fueling issue. Can you datalog and send to your tuner?

Hows the maf, connectors wires ect, no pinches or cuts, is it plugged in?

Are you running a BAP?

Definitely sounds like FRPS issues. After one goes bad, it will take a little bit for it to clear up. Rich smoke is somewhat normal after it floods out.

Thx for all your replys, so i am 100 percent sure about my tunes. It idles and drives when i return to stock and it Dies rich and smoke as hell on the All the remote tunes from base to final.
I dont think there is a problem with the tunes but some kind of issue that comes to light because the tune does something Different the the stock one.

I could only datalog the return to stock tune because otherwise it wont run. I am waiting for a reply of the tuner.
Its deffinetly a fueling issue, it is fully rich on the gauge, smells like fuel and my rear bumper is Black like it would be a diesel

The maf looks good, connectors are fine. Only thing thats strange if i unplug the mafia and run directly the stock maf it does the same as with mafia. Mafia is Set to 0.
No i dont run boost a pump
The pumps are new and seems to work, i can plug on of the car will be full rich either. On stock tune one i can unplug the pumps seperatly and it will run.

If the MAFia is set to 0 why are you running it? Was it set to something else when the tuning was being done? What happens if you disconnect the MAF entirely?

So i am at the car right know there is no difference in maf unpluged, mafia unpluged mafia setting to 1 (should lean out)
The mafia is there if the maf would peg but it was Set to 0 the whole tuning process
So my guess either the mafia or the maf are dead?

If the MAF didn't peg I would remove it. My hope was that the engine would run better with the MAF unplugged. Since it didn't there's still a problem somewhere. I doubt it's the MAF or the tune. Tunes don't randomly go bad.

You said you did a pull then shut it down. Have you checked all the vacuum lines? Granted usually if a vacuum line is popped off it'll go lean, but I've learned to expect the unexpected.

I was just saying to keep an eye on the pumps. Mine started working out fine. Then one day I started losing pressure at WOT, but everything was fine at part throttle. Turns out one of the pumps had died. After some digging I realized I was mistaken in thinking they could be run in a returnless set up.

Yes i did a pull on the Highway and after that i cruised along the Highway till next city. Drove a bit further and after 20 miles or so i stopped for food. After this the problem was there.

So all the lines are on, dont have that many because of the egr delete, only Thing i couldnt test was the lower intake, i plugged the pcv there

Short Update did a smoke test no leaks.
Maybe its the O2 Sensors?

So i unpluged the new frps, car runs.
How big is the Chance the new and old frps fails electricaly?
Is there any other thing that can cause the car to run Smoking Black rich with the frps plugged in?

I remember dealing with this. It was something in my tune. Went with Malcolm for tuning and it wasn't an issue anymore.

But why was everything ok at first?

Kevin hast tuned my cobra. He is a well respected tuner. I trust hin so i dont think its in his tune.

Btw i get 5 volts on ignition to the frps so cable and signal should be ok

Actually if i recall Malcolm had me change out my Deatschwerks injectors to Injector Dynamics. He said he could have made my deatschwerks work but with where my power level was heading and there being more data for the I.D. it woulda saved me a headache in the future. The Deatschwerks were my issue

Ok i hope mine are fine, they are 200 miles old

So i changed the frps 3 times, car wont run with any frps plugged. If i unplug the frps it runs, if i load stock tune it runs.
I get 5 volts to the frps plug so i dont know any more

Sounds like it's time to talk to your tuner.

Can do you do any logging? What are your STFTs/LTFTs at? FPDC? MAF counts? Fuel pressure? I would especially be interested to see if the fuel pressure is rational. Keep in mind that in my experience the car has to be running for the fuel pressure value to update- that is to say it won't be current/accurate with key on, engine off. It also freezes at a value when you unplug it or shut it off.
