Guys, I am about to get 264's installed in my car. I was wondering which VPC chip you are using for the single turbo with cams. I know that HKS makes the C chip for this configuration but I have heard that it it would run too rich on top. I am currently using the B chip (single turbo no cams). I was wondering if this would be too lean if all the settings on the VPC and the S-AFC are set at zero

Stick with the B chip. The C has major issues in the 2.5-3.5k RPM area.

VPC CHIP

I have the same question. I have stock cams, upgraded fuel, and single turbo. I have just added cams and was wondering which chip to use. Currently using turbo/fuel chip. lmk Thanks Richard

I agree with jackdoe -- I'd recommend sticking with the B chip. I've run both with single and 264 cams and I don't like the C as well. My main issue with the C is somewhat poor idle as compared to the B. I've also HEARD from a reliable source that the D chip is good for single and cams, but I haven't tried it yet.
