What I meant was the PCM calibration (programming data), which is for a 2001 model, yet it works very well in my 1999. Now that doesn't mean it will work in your car for sure. But, if you can get a 2001 Alero PCM to work in your car, it should allow you to use the 28 lb injectors until you can get it correctly tuned. Either way, it is best to have an extra PCM module.

where can i get a PCM tunner for a 2001 alero? could you link me AleroB888. Would i get any stock protential using this PCM tuner in my alero?

You are going to have to get hptuners like was said, so that you can custom tune for your individual setup.
