OK I had a loose plug wire. It was not the Trinity- Mea Culpa

I am back to the stock tune and disabled DOD.

Will check the version

No Pontiac 2009 G8 GT. Sorry multitasking....

I loaded the 91 octane tune-

I did not check the version - how do I do that?

Car has 99k miles and I just put new AC iridiums in it 3 weeks ago. It was running fine.

2009 G8 GT stock.

I got my Trinity and installed the 91 octane tune. It was more responsive but had a bad shaky/rough idle- like a miss. I adjusted the idle up150 rpm and somewhat better. Then a p300 code popped up. I cleared that and reinstalled my stock tune. Idle is still rough. What gives?

Not happy.....
