I have a jdm b18c(gsr) with a cai, Skunk2 intake manifold, skunk2 stage2 cams, DC sports 4-1 header, carsound highflow cat, apex n1 exhuast.. Right now I have my vtec cross over @ 6,000rpms, and I have it set to go from high to low cam profile @ 5900 rpms, but under agressive driving when i up shift i kinda bog around 5,000rpms.. I'm wondering if I should lean the part of the map or make it richer?

 

Do any of you, know any settings that worked for you with a similar setup?

 

What's differant about the new vfac II from the old vfac?

 

I believe it has more fuel ajustments, instead of every 100rpms you can ajust every 50 rpms

 

Nobody will be able to accurately tell you what to do with your settings. You'll have to bite the bullet and go to a dyno w/ wideband to get your power curve ironed out.
