Yeah, I plan to pick up some gauges.. boost, fuel and EGT.... probably not worry about the trans temp since it's a manual.
As for the warranty:
I called the local dealership and the engine is good through 100k miles, I can pay a $150transfer fee to get the Powertrain (transmission, axles, etc.) extended to 2012 or 70k miles so I'm going to do that tomorrow... I meant to ask if it included the clutch, etc... I'll do that tomorrow as well.
As for modifications, all i'm looking to do is an Intake and Exhaust and I don't think that will void the warranties.
