go with what the local tuner suggests, that way, the tuner has some experience tuning the setup, and if stuff goes awry, its easier for them to pinpoint.

yeah people say its all in the tune, but there are other factors that can make the turbo experience suck - namely installation issues (think crappy oil feed/drain fittings and bungs), current engine state (if he's got engine issues now - even if they're little, they're just going to be magnified x10 when he puts the turbo in).

its not for the faint of heart. but if all the obstacles are overcome, its a very rewarding experience.
