I installed the new FPR and boy what a difference! But...not fixed. It does get into boost MUCH smoother but it still face plants. At cold idle I am getting 10hg vac now and it is very erratic. I can drive it around, stop and let it idle and it has 17hg and then I can drive, stop, let it idle and it has 14hg. The rear turbo is still glowing but I really think that, the rear head has been the problem from the get go. I am thinking that the guides are shot and causing the valves to not work properly. Only thing that is weird is that I had the heads rebuilt.
