I am about to do some upgrades to wifes 05 gt. Can someone tell me what the rwhp is from the factory???? I am installing long tubes, off road, and bassanis, along with pulleys, air intake, and tuner w/ custom tune. What should i see from this??? And who do you recommend to do the custom tune???

 

about 265RWHP is about the average i saw at the local club's dyno day for a 5 speed.

 

ok, so hers ia an automatic, so maybe 250?

 

yeah. somewhere 250s for an auto. might want to ask in the 05+ section to see what most of them put down. i'll move it there for ya though.

 

I would say about 260-265 RWHP stock . Maybe about 310-320 with Add-ons.
