    I love my GTP. I've had plenty of V8s. I like a SC V6 that I can work on. If you compare a GXP to a GTP it's close enough. If you compare a GXP to other V8s it seems to come up short.

    Biggest issue is the ls4 and FWD.

    Hell i think it wouldn't come up short if it were just RWD

    The instant response is no comparison to my old GTP. It was stock, but I thought it was pretty quick until I drove the GXP. I had to have it after that. Not to mention the sound of a V8 is bad ass, coming from a Grand Prix at that... I cant tell you how many people have approached me asking how I got a V6 to sound like that lol

    I agree. But I think you may be talking about a G8.

    I'd love to have a GXP, would love the instant throttle response from a NA V8, but i feel like the GTP will be best in the end. And of course i live in Mexico

    Doesn't have to be tuned. I heard different states have different rules on tunes. Specifically California. Not sure about the rest. I could be wrong though. But, I really meant "boiling" at 25, not so much breaking loose. There's at least a 5 second burnout from a dead stop when I push WOT. lol
