Same for my 6.2L. 125 shot... Started small and worked my way up to 125. Was running dry through MAF, but it ran rich without tweaking AFR's. I would be interested in seeing how others have tapped the fuel on the direct injection.

Where did you find your spark plugs?
I couldn't find any with the proper depth.

If that's how I am reading this, you're about one short away from a firey show.

i learned the hard way on my car projected plugs are a no, no i melted some and in one cylinder as the porcelain exited the valve closed and broke a peace out of it, the main reason for the br7ef is its a non-projected tip so it doesn't get as hot

at the time i was only spraying a 100 shot, with the br7ef plugs i'm @ 150 so far no problems

if your using projected tip plugs i'd swap to non-projected

I'm spraying a 150 single nozzle kit on stock plugs and so far no problems. On my second bottle, need to have it refilled

plugs are cheap why gamble? sure i got away with it for a few bottles but my luck ran out.
