When I take off from a traffic light at full throttle in first gear everything is fine. When my car shifts into second and I am at full boost my car starts to sputter almost like its hitting a rev limiter. What could this be? Could my spark plugs be shot? When I am driving at normal speeds and not at full throttle the car seems to run fine. Any help would be greatly appreciated.

Are you letting your car warm up completely before you get on it and are you running a different heat range plug?

I had this same problem a couple of times. Sometimes it did it, sometimes it didn't. My car is ripped apart now so I can't help you very much, but I would say change your plugs. How many miles do you have on them. 3330's only last about every other oil change.
