What kind of combos are some of you guys running on the 2.2. I wanted to run an upper and a lower. Right now I have a 6lb lower on the car and 3.25 upper will be on the Kenne Bell. I was guessing that would be about 19lbs? How much would a 4lb lower be with the 3.25 upper? I want to run 93 octane. I guess what I am really asking is what is the most boost you can safely run on 93. And what upper/lower combo best acheives this? Thanks, Ryan
