Thats great power your making! I wonder why that was with the fuel system?
I suspect a tired 6 year old walbro 255lph pump is the culprit. filter is relatively new (about 1000 or less kms old). Whatever I did with the fuel map & regulator, my AFRs at 8k and above rpms stay the same. I'm going to replace the pump this week with a 340lph Aeromotive one but I don't think I want to push it anymore power wise because NOW I'm realizing that I can't afford to rebuild a block if I blow this one up. lol
