Mugabetown - Whoretownin' At It's Worst.

Was a lot of fun, the SS is a pig to skid...the benefits of a car up for track. Also she has started running really lean under load, anyone have suggestions on a cause? I suspect the fuel pump but don't know how to test it.

test voltage of fuel pump
I would mate. But no spare cash FTM and that would mean burn more money for 50kw. Not chasing more power anymore but focus on handling, reliability and response

Those turbos will be more responsive than your existing ones supposedly. 50 (or more) extra kW is just a bonus.

But yeah, cash monies are the problem. Would be 2k out of pocket in the end.

My car started running really lean for 1 dyno run yesterday, the tuner 1st thought dodgy fuel pump till I told him I bought it off him less than a year ago lol.

Turned out that a tiny vac hose going to the fuel pressure regulator had come off under boost. Anything like that on these engines?

If nothing simple like that, fuel pump and filter are next to look at.

    • Was that with the cas upside or correct way up?
    • Did and sync timing with light 
    • Have you done the Ignition Sync Wizard in the AEM software?
    • Find out what RPM it was idling at with the IACV unplugged. It's very weird that the rpm didn't change at all, and then it stalled. When it stalls is it nearly like a switch off, like you've turned the engine off? Or is it more stutters and sputters and coughs to death over a few seconds? Or does the RPM just slowly keep going down and down? Have you done a test of trying to start it with the AFM unplugged? Does it still die?     If you Follow Josh's advice on using Nistune to check the voltages (which is a perfect method!) if you see anything out of wack voltage wise, THEN get the multimeter out and read the voltage directly at the sensor. If the two vary, then you're now looking for a wiring issue vs a sensor issue. So be aware, what the ECU sees, may not be what the sensor is actually saying too...
    • You very likely need to get it on a dyno and tune it. My assumption is, you've got an RB25DET tune in it, which has a different manifold, different injectors, and different cams as a minimum. What O2 sensor are you running?   When you say it runs extremely rich from idle all the way to redline, is this just free revving it you see that?
