Check if there are any trouble codes with the VPC/GCC installed. If not, you just need some tuning. Try playing with the knobs and see if you can get it to run decent then drive it (carefully) to the dyno or, buy a datalogging wideband for yourself.

If there are trouble codes, they will need to be diagnosed before proceeding.

Where is your temp sensor and MAP sensor tapped? Did you relocate the ISC? Did you remove the stock AFM and put a pipe in its place? Did you use the HKS harness or hardwire it yourself? Just trying to get a general idea of how your instal went.
