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
 
nice build, gotta respect starting with the lowly base models (EK2/EJ9) and going big
 
finally managed a 607whp on the dyno with some cam gear tuning and more boost, and a very cool intercooler lol. fuel lines were flushed, filter changed, wiring was checked/cleaned and pressure was raised, solving the lean out condition seen before. ended up boosting 27-28 psi. managed 1 607whp pull but after 3 more runs the average was 596whp.

unfortunately, the Skunk2 Pro1 camshafts along with the JG Victor X Intake Manifold will be returned to race car as it's engine is being assembled again right now, so it's time to return to the Type-R intake manifold / ITR cams setup. will update people on this and I'll see if I can do better than the previous 530whp dyno with the OEM parts.
