I am going to be dialing in the car on a dynojet dyno with an O2 sniffer. Are there any suggestions on the best way?
I have a T64 with stock fuel for now, VPC, GCC. I was planning on running about 16psi at first to see where my O2's are at and am going to adjust the boost to get around 500-525rwhp depending on how my A/F is doing. I was going to dial in rich and slowly lean things out to get the A/F dialed in. Where should it be? Are there any suggestions?

Im just trying to get all the info possible because the tuner mainly deals with Mustangs etc so... Thanks!
