I also am not a big fan of the hahn manifold or turbo.
I will also support the fact that Hahn did not fudge their performance numbers. I was one of the beta testers for Stage III with my previous solstice and I personally dynoed the car that I installed myself and got 300whp with Stage III. Hahn then took that information and put it on his web site. So I believe his numbers. However, every dyno is different and there can be variations because of that. A dyno is just supposed to show before and after gains. I was at 254whp with Stage II and then increased that by 47hp with the Stage III upgrade on the same dyno.
I now have the Hahn development car and it gets driven hard. I personally have had only a few problems (that I didn't cause myself). But again, if you want to run this kind of setup you have to be willing to get your hands dirty every now and then. I can say that I have put about 30,000 miles on Hahn equipped cars and I am still going strong.
