If you need to start a thread asking how much then you shouldnt be touching anything. You obviously don't know what to do next. Hire a tuner to travel with you and make changes as needed to hit the numbers you want. it will save you a lot of aggravation and you car will go quicker without "pushing" anymore boost and much quicker when you do. If you're interested I'd be more than happy to recommend.
That's pretty funny $hit. Dave has kept his car together longer than a vast majority of the Buicks that I've seen around his current and much slower speeds. He hasn't spent a $100k + in blown up stuff trying to get there. I'd say he's doing ok.
