Zoonhollis,
I was interested in doing the boost adjustment as well. But with a car of this age, I figured that the cost of a new engine and/or transmission isn't worth getting to 60 a few seconds more quickly. Additionally, I didn't buy the 300D to be a speed demon
It's not like a Toyota Supra, in which you can crank up the boost to crazy levels and get 600HP on stock internals. But thats a WHOLE different story.
