Hey Guys, my suspisuion is a cracked ringland when we first started tuning it. It was a little bit low on 93oct compared to the other 1.5 cars I've done even though he had a smaller pulley. When the motor let loose watching the data logs the knock went from -1 to -10 instantly and let loose. AFR were good and power was climbing right up till the failure.

As far as the gauge we noticed a drip coming from the gauge after the dyno sesion. At no point did it leak or spray fuel in the dyno.
