My dad decided to get a 2005 Sonic Blue V6 because the GT was out of his budget. I am very impressed with the V6 and am going to register him with the forum, too. B) He wants more horsepower, do you guys have any suggestions. I looked at the SCT Xcalibrator, what HP gains can you get from it. And does the Underdrive Pulley help out. We our trying to get some more low cost horsepower. Your comments are appreciated

 

Any replies?

 

I'm waiting on the GT myself, but look up at the top of the main 2005 page and there's an entire section for v6 performance. Look there, I'm sure you'll find all the info you'll need. Congrats on the great car.
Good luck.
