Do you know approx. how much for the tune? I'm interest, but thing is, I have pretty same set up like yours plus pulleys, thermoblock spacers which might/might not need to re-tune.

Re-tuning the Unichip will depend on how much your local shop charges. The thermoblock spacers will only impact heat soak issues and not A/F ratios. I'm not sure if the pulleys would have a negative impact though.

Why not just pick up a set of XS headers?

The tune is based on the A/F ratio curve that the engine produces. Since the A/F curve is directly influenced by the intake/headers/exhaust used the performance of the tune would be directly impacted if one component wasn't balanced. This follows the practice that you need to have a balanced engine ie. your ability to pull air in must be balanced with having a free flowing exhaust.
