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!

Hi Kevin,
