Need some advice on custom tuning. Basically I was looking to dyno the car just to see what kind of numbers it puts out, as the previous owner, who himself didn't build the motor, had never had it dynoed either. Now I'm faced with the option of custom tuning, which from what I understand can get expensive. I'm wondering if I should bother spending the money; money being a bit short right now. The car runs great, no problems so far (knock on wood). It's vortech supercharged and running an FMU. The shop tells me I would have to get rid of the FMU and most likely get larger injectors. Also, I need to get an o2 bung installed, among other things. Is this true? It's getting expensive already. What would you do? Run the car, get the numbers, and walk away? or prepare to spend money? Save, then get it tuned? Like I said, the car runs great, would tuning be necessary at all? Could evil things be lurking even though it seems like it's running good? Need advice. Thanks.
