Ouch !!!! :doh:

I'm saying my prayers now that my engine is still OK. I didn't notice anything afterwards. Had the Procharger kit on 1 day when it sucked in the elbow and broke the compressor. Now I get it back together after 3 weeks and then this happens 2 days later. Some of us just have no luck with modding cars.

Just looked at the log in excel and the knock was at .5 at 6500 where it looks like I let off. Not sure how bad that is though.

How did the spark plug look?

So I pulled my code today and it was P0300. Multiple cylinder misfire...YAY. It's more fun when you don't know where it happened.

I'd pull your plugs and double check all the gaps. Mine are gapped at .030 for reference.

I'm going to as soon as I get the chance. I set the gap at .032 when I installed them. I gave that info to Lund before we started tuning but it appears he may have ignored it because now he's telling me to use .028 - .030.

Sounds like the spark was just getting blown out at high RPM/boost.

How many miles on that?

Here's my #8

Is that carbon on the rings and piston?
How many miles FI before piston cracked?
Thanks for posting up the pic.

 

[RockStang]

I'm curious what it sounded like when that piston broke. I'm assuming it made quite a racket. We're you still able to drive it all?

turbo50 was a tune issue.
