squeezing full HP out of a GTS

[Slamstadam]

Once the typical bolt ons have been done- K&N, smooth tubes, Headers, full system. Is there significant HP to be gained with a power programmer or PCM flash? How much gain on the Dyno?

You might gain another 15-25HP from an SCT tune. Contact Todd at A&C performance. He probably can give you more specifics.
