Basics I've learned with 3+ years of ownership and FBO:

Maintenance before mods. Mods will exacerbate existing problems. Get the
car running great then mod. Expect problems once modded (misfire, various
codes etc). The forum can help you sort it all out with proper logging.

Power/results for dollars spent in order (my opinion):
  • Tune - most here end up with a JB4 + Flash/ecu tune specific for their set
    up. Some are happy with flash/ecu only tunes, I prefer both
  • Fuel (octane/ethanol), ethanol is easy and if you add an ethanol tune=Wow!
  • Everything else to support/push the tune and fuel (charge pipe, BOV, exhaust, fuel pumps, meth, and on and on)


Mod, Log, Adjust (fix, repair), repeat
