Tpis ls6 worth it?
not saying the benefits weren't there, but the asthetics were lacking.
with 390hp...the fast will be a good upgrade. i gained good power with mine. search my name in the dyno section and you'll see the results.
by the time you spend the money for the 90mm upgrade, and the new TB, you are damn close to the price of a FAST with the TB...minus selling your ls6 and stock TB.
proven power....
