Mods on my car wett 1 bar chip, boostvalve mbc, ghl down pipe. Prior to installation, I was spiking to 20, and holding 17psi, tapering down to 11 or 12 to redline. After installation, car goes into limp mode no matter which spring in I use(stock or chip or mbc removed). Any clues as to what is going on. TIA.
