    9-3 Sedan, Cabrio '04+, Combi, 9-3X Workshop
    I'm looking to upgrade to a 19T and larger injectors from Vtuner Stage 0, and the quote I recieved from JZW was about 900 bucks cheaper than the comparable Vtuner upgrade. I have a few questions for the V6 owners running JZW tunes. I see that John uses GM I-flash. How does this compare to HP...
