" If motors are blowing up something is seriously wrong somewhere. You know how hard these motors are to blow up?
Here is a prime example, and it happened last night while doing some boost, EGT, and BP logging on the shop car. Running the mega aggressive 558WHP/619WTQ tune, WITH a few extra PSI added for good measure I am doing a 2000-redline pulls in 3rd. Mid-pull 29+ psi, 15 degrees of advance, 5500RPM meat of the powerband, number 2 injector plug somehow vibrates out, dropping all fuel to number 2 cylinder instantly, log is a scary thing to behold, bank 1 afr jumping to over 15:1 and HPFP dropping all at the same time. SOMEHOW the DME being the magic box it is, catches it and throws it into limp, I pull over check codes, #2
injector malfunction, hmmm. Pop the hood find the plug out just quite not seated and am 100% sure when I fire it back up the idle is going to be lumpy still with a torched cylinder. Fire it back up, dead smooth do 3 more pulls at these levels, logs are all perfect. In ANY PI car that cylinder is gone if something like that happens.
The point of this story is, if the DME can work its magic to protect the motor in a situation like that, you must really be doing bad things to lose one of these, from a lean / knock condition. "
