sicksaleen94....are you sure you car is in proper working order? From what you describe you have a very mild head/cam/intake package. Your complaining about breaking up at top end. Not that a tune wont help (it will help alot) but for what you have the stock computer should be able to handle it.

Yes the 94's came with the hypereutectic piston, while not as strong as forged they will handle a shot of nitrous no questions asked. Beleive it or not they are stronger than what most people make them out to be.

Put a 100 shot on it, back timing down 2 degrees, and drop the spark plug one step colder and gap to .035 and go have fun!
