vpc with a ?

[lodder]

Hey boys thanks for the info in the turbo of choice. Now for tuning aspects. I figured I can get a vpc for a good price. (Gotta get rid of that mas air meter) It's just that I need somthing to tune the fuel curve. I've heard that the gcc is a bitch to tune with. Some say that the apexi s-afc's are really good to tune with and my friend has an HKS s-afr. He thinks it's a great tuning device as well. So basiclly, I need some input on what you guys have been running in your set ups and what has worked well. Or other routes.

Thanks,

lodder

If I throw in plug and play injectors, will I still have to change the rom in the vpc?
