After 30,XXX plus turboed miles, my HG just said uncle. I'm too broke to rebuild it right, but I am interested in rehashing the TTI hg arguement. I searched and got more or less of the same arguement of lowering the compression of a motor with more boost will not make more power than stock comepression and less boost. If anybody is actually (or has used) the TTI gasket, lemme know what you thought. I'd like to get the car back on the road and start driving it again.
I used it for a couple of years. Seemed to work ok. I would say it does not make more power but makes safer power on the stock internals. I doubt your butt dyno would even notice the differance.
