I finally strapped the GTO on the dyno sunday, it put out a lot more than I was expecting. I would have been happy with anything over 320hp.
It laid down 344hp/353tq.
That tells me the engine is putting out every bit of the 400 rated hp.
just thought i'd share it,

hey bud8, sorry i missed your call, i'll give you a shout tomorrow, ya, i like the numbers,
after i get about 2K miles on it, we'll see if it increases in power, most say they put more power to the ground w/ more miles. i'm hoping for at least 20hp from a tune, i just hope it's detuned like the '04's are. TM is really killing this thing.
later,
