I have a 2011 R-Spec. My mods are a dynojet cmd with 20psi tune, 02 pipe, downpipe, catback, intake and BOV. My tune is great until this.... I will be driving and do a nice pull and then suddenly i will shift down and try to do a pull again and boom, only boosting 4psi. I am missing my top stud on my 02 housing which causes and exhaust leak, I will be getting it fixed on monday, but I am wondering is this whats causing the "limp mode"? Could the first 02 sensor realize i have a leak and thats whats throwing it off?
