trifectaperformance sounds interesting and I will visit them the next time I'm in the Seattle area (2.5 hr drive west).
Note: What they are doing sounds very similar to what an HPTuner setup can/will do. An Alero CAN be tuned the same way, in fact I had to put an Alero ECM in my Malibu in order to support the S/C (GM dealership reprogramming so far). I have logged some data with my HPTuner already but had kinks to work out before doing any real tuning.
Unless a particular shop already has a tune in hand that matches your setup expect to pay for at least a half day of technical services. A dyno may not be required but should make it faster/easier to do. If you truly need a custom tune you already have spent enough cash that another 500 or so won't blow your mind. Do it right and you won't be blowing motors... been there.
