First, the standard tuneup regimen-cap, rotor, plugs, wires. all filters. If you have a K&N filter, I'd suggest cleaning the AMM with a suitable cleaner. Injector cleaning is also a good idea. Check intake/turbo hose for cracks/holes and make sure clamps are properly positioned and tight. Never hurts to replace your vacuum lines with silicone hose. With these done, you now have a reasonable starting point. It's also nice to have the appropriate manual handy, to ensure proper settings and installation.
Following this, I would check timing, fuel pressure, and boost levels. This should give you some idea as to where to look further, if necessary.
Good Luck!
