COBB Tune: Typical Stage1, Stage2, and STX vs. Stock Power:

[LaszloT]

Maybe I can get a part-time job at COBB, and get paid with a COBB Stage2 Power Pack..?

These power improvements are $exy! :)

Those are nice increases from stock to stage 1 considering you don't even have to open the hood.
But all the fun is lost. O for the days of swapping out ingition modules, jetting carbs,manually adjusting timing. O want stage two, change some exhaust pipes and flash away. Old way, tearing. Open the engine to change cam valve springs intake manifold exhaust......

O Right thats why I sold the carberated v8. I'm getting lazy lol

Getting rid of the cats for Stage 2 is the best choice. Going to a linear throttle map is also wonderful totally changes the Subaru gas pedal from an on/off switch to a linear adjustment.
