My EFI classmate just got a Dyno Dynamics setup in his just opened speed shop. The second car to roll on his new dyno was my y2k c5. With a ZO6 catback, a lid, and a street tune, it dyno'd 334rwhp!!
Enzo from Dyno Dynamics assured me it was an accurate. [brand new!!] dyno.
Kooks headers, x-pipe and wideband sensor are in the works!!!
As soon as I complete these mods I'm visiting Leroy to see the results
