FGED UP Member 28 Member For: 13y 5m 2d Gender: Male Posted 18/08/13 10:55 AM Share Posted 18/08/13 10:55 AM my ute is tuned to 98, the other day my old man took it out filled with 91 unknowingly. I went out the next day and could hear a ticking noise took it to my tuner straight away. He said someone filled your car up with 91(think he called it pinging), had I giving it a good squirt it could have snapped pistons or put holes in the engine.

Can someone explain what this means and how come our turbos don't do the same when tuned? Link to comment Share on other sites More sharing options...

If I'm reading things right. Link to comment Share on other sites More sharing options...
