Hondata FlashPro tested in CL9 Euro - it works !!! TSX 07-08 ECU required.

Call me a noob but am I to believe we can get over 30% more power just with a tune?

all depends on car mods, tune is a must for car with other camshafts, headers, intake manifolds and etc. Mount turbo without a tune and I get you +50% with a tune easy.
