Brainstorm: Ignition breaking up on dyno

Fp is very bad.... the hot wire kit helps keep contsant and max power happening...but not a necessity.

Replace the fuel pump first. That could clear up all the issues. You may be showing good pressure initially, but if it's dropping and you've obviously got a bad pump, replace that before throwing other parts at it.

Thanks for the replies guys. He's ordering a pump, hopefully that will clear it up. Update after part is in. Fingers crossed

That doesn't look like opti breakup to me, judging by the graph. When mine was doing it, it was very obviously an ignition issue. I was going to say a possible fuel issue before I read the fuel pressure problem. I would definitely get that pump replaced before screwing with the opti.

Probably fuel. But its worth checking out everything. Nothing wrong with double checking everyting.
