Plugs are absolutely fine, the car runs okay on idle at 11.8 and runs well at any other RPM/load other than idle.
Fuel pressure was checked and is fine, injectors are also okay.
I'll start the car up tomorrow, warm it up and send you guys the log of me switching between 5 and 6 VE
Also, about the corrupt tune - it happens on 3 different cars, it's just the most extreme case in the 1JZ. We had two different boards tested, two tunes and two different laptops
