The second turbo does not come online at all. This usually happens when the car is cold. I warm the car up and when I first go WOT, the second will not come online. The next time I give it WOT the second turbo will come online and everything works fine from then on out. This doesnt happen all the time. Only every now and then but has become more frequent recently. The car runs perfectly other than that.
Any suggestions?
