What sort of power gains can I expect?
Hondata collated the results from a recent 04-08 TSX dyno day using a non optimized reflash.

This K47Z7 engined 09 TSX was baselined at the dyno with a test pipe, 06 Civic Si intake manifold and replacement air filter. All gains (35 hp) were made from FlashPro tuning.
