working in the boot of his car paid off today, AFR's are doing exactly what i wanted tonight. Just got back from a drive with it. went down to the servo to top up the $21 worth of EFLEX, racked up some sensible km's, think we are up to 50km just cruising around with a few squirts on 14psi low boost, and only 1 half throttle tyre fryer on high boost, got scared as midnight and tired, had a big day.
Maxed out at 367kw on 22psi, tried more boost with no gain, but very impressed as its all legal in the way of Catalytic converter and wastegate plumbed in, thing is a sleeper.
still got to finish the tune back from E67 down to 98 octane but atleast everything held together
