Yeah, new fuel pump and fuel filters, especially if that was on your list anyways it couldn't hurt. Do you have any way of monitoring fuel pressure while it does this fluctuation?
I guess I could look. I have the B&M in-bay gauge so when I first start it I could look at it. I'm running 40PSI when it's at normal op. temp. and I know stock GSR is 36 PSI, but I'm at 9.5:1 instead of 10:1.
Also, I have a brand new AEM filter, rail, Venom injectors, and B&M fpr.
