fuel pressure should always be set at the factory setting of 40 PSI

I disagree, when I added my headers and pro-chamber to my catback I was instructed by their tech to bump up my fuel pressure, adding a bunch of power is going to lean out your fuel, therefore you want to add the correct amount of fuel to your combo. I think you need a lot more fuel....glowing headers are from being leaned out real bad, think about having too much fuel, it'd be blown out your exhaust and going through your headers to get there, cooling them down actually. Might wanna get some dyno time on a dyno with wideband support
