Hello. I would say the Diablo Sport Predator or Trinity. I run the Predator on my car, SRT-4 Neon, and love it. This is just my opinion that I formed based on modifying my car, please form your own since you have an entirely different vehicle.
I highly recommend joining a forum dedicated to your particular vehicle, do a lot of research before purchasing anything, read, read, read, then read some more. Then start asking questions to other members privately, and the last step would be ask questions publicly if you can't find your answer. A lot of automotive forums have some real jerks and will make you feel like an idiot if you don't follow these basic guidelines. Trust me, I know from experience!
I really hope this helps the least little bit so that you get more excited about your vehicle. Sorry to write a book but I like to share my experiences to help others.
Richard
