Your log has conflicting data, #8 is misfiring but you also have a goose egg in total misfires...

You are also not logging fuel pressure. This is an essential. These are the minimum I ask people on Hellcats to log... everything else is gravy.

obviously the widebands wouldn't apply to you but you get the gist of it.

please show us your fuel mass vs inj pulsewidth table and tou inj pulsewidth vs fuel mass table.

additionally what is leading you to believe that the #8 keeps going out? Im going to look at the last log you send me again with a magnifying glass

You should have the tune I sent with log.
Before the new PCM went in I scanned getting info for Computer Repair shop, showed P0308 code

I'm setup to log 1-8 misfires in scanner.

Fuel pressure is in channels, added to charts now. KR showed as fuel

This was right before the belt broke.

With that boost you may want to consider plug gap playing into it.

Guess I could tighten up the gap and see what happens. Was at 23 with Brisk, have them at 25 with NGK. Could go down to 20 and see what happens.

On that cyl anyways eh?

Just #8 now to see.

Finally getting the proper Dyno tune from N2speed at AMP. Chris was able to get the old ECU to get past the 200kpa limit. Just a pic of first results with the 2.75 pulley on. No HP numbers, still working on tune. Looks like either a third pump and or bigger injectors are needed. Running FIC1200 now, E85 tune. He said it's running rich, so IDC should come down. Depending on that, I have the 2.5 pulley to go on, maybe 19psi.

May need to get the 15" conversion in back, 17x11 305/45 M/T now.

Niiice. I think 1200's are plenty. If it's rich, the pumps aren't the issue.

As for the wheel size, the MT Street R's 305/45/17 will hold every bit of power you can throw at them.
