im on a minsy 14b. did a little more research to find that higher octane = lower o2 voltage readings, I should probally mension that i get .86 on 93 so my 02 voltage is right on as far as the 1g's are concerned. I'm thinking now that the low voltage was just the 110 and my only problem could be the heat soaked intercool. but I never seen anybody with problems like this with sidemount and stock turbo. I mean shit, I had another friend run low 14's with stock side mount on a 1g fwd. my car did a 16.0 @ 88mph WTF??? and 88mph trap will tell you its not the driver.
