I feel the same way as you. I am at the point where mechanically and cosmetically my car are very sound. I have a solid 330 hp and 350 torque with the usual upgrades. I still too think about crossing that invisiable line to pull the motor and go for it. I think at this point my goal is reliability. I know what my cars potential can be, and I think after a few more mods here and there to get me closer to the 400 mark on stock turbo's and Im gonna just have fun using my tt as my weekend stress reliever. I just dont want the car itself to bring me any stress. Hats off to all the 500+ horsepower guys, I went down that road in a tt audi s4 and it got to the point that every couple says it was somethinelse and i just got tired of the stress of the car. I say have fun and be safe.
