GTR running full lean after the dyno

Recommended Posts

Looking for any and all insight on an issue im having. Took the car to the dyno and ran 100% perfect, on the way home while cruising the car went full lean 18+ afr and now idles there and drives full lean all the time. and to get the car to start I have to pulse the injectors from ecu then crank the car over.
Small car details 2200CC injectors, E85, Dual walbro 450s, Adaptronic ECU ect..
Fuel pressure at the rail is steady at 50psi and I've pulled return line off at the tank and primed pumps to make sure its flowing fuel and not a plugged filter or line. Swapped spark plugs, Compression is perfect, Boost leak checked, Car idles at same vacuum as before, Checked timing, Tried swapping the CAS. TPS is good, Water temp/Intake temp sensors are working. ID2200CC dont have filters so the injectors can't be plugged either.
I was thinking the injector wiring but I can pulse each injector from ecu and hear them click and watch the Voltages/Amps going to them.
I'm stumped at this point and would appreciate any advice.

    • VP race fuel like VP 109 ron unleaded is a waste of money compared to E85. Just go flex fuel setup so you can run on pump unleaded or E85 all without draining tanks or switching tunes. You go VP race fuel you will have to change tune when using it, then change back to a pump unleaded tune. VP109 for example will support about the same boost and timing increaes as E85, but it requires the afr's to be a lot leaner than E85 but richer than pump unleaded.
    • Whats your budget? Maybe call Nispro in QLD for quote - they build a lot of VQ and have a turbo kit in development - but id say at least 20k to do it right - oh actually maybe do LS swap will be cheaper but....hmm  im a purist - so id rather stick to VQ35DE or whats the point lol.... just my opinion - do what u want. its your car  
    • Ok sorry I should rephase my question. But good answer haha.  How can I make 400whp that isn't using nitrous. 
    • dyno run would be on VP race fuel or e85 / e98, E85 is not easily accessible by me. Closest pump is 30 min in a direction I do not travel. So while I will go out to get it. It will also get pump gas 93 octane is highest avilable in US so overall power will be down if mix fuels  e50, e30, e10 ect 
    • Cheapest way? Spray. A wet kit with 200hp jets could be up and running for less then $2000. Then its about $16 per pound when its time to refill your bottle.
