Message	I have now had my 91 ttz for about a year, and since buying it I have had a recurring, very annoying problem. It had boost jets when I bought it, and only the stock boost gauge, but from what I could tell, when the car would boost up to about 14 on the stock gauge, the power would cut out. I finally got my Blitz boost controller in, hoping I could pinpoint the problem, and I found that the car when it hits 12 psi, sometimes a little more sometimes a little less, will lose power. It's hard to explain what it does, but it doesn't lose boost, the boost stays high, but at 12 psi or higher the engine noise dramatically changes to a weird muffled strained sound and I lose a noticeable amount of power. I have strained my mind for the time I have had the car and still have no idea what is causing this to happen. Any ideas?
