If you're looking for power mods, there are some good vendors here. Livernois Performance, OST-Dyno, etc.
Paul with PK Auto is a newer supporting vendor, and he hooked me up with my 3 modifications: wheels, Borla S-type cat back, and Eibach lowering springs
You know the drill on what you can, and can't do, as far as voiding powertrain warranty, and whether that is even a concern for you or not.
I have modded _every_ vehicle I've owned (well, except my wife's... she would not be happy with that) for more power in the last 25 years, _except_ this one. I've had mods sitting on my garage workbench before the car even arrived. LOL So I consider myself a true hot-rodder. But, I've left this one stock for just over a year of ownership. It's just that good of a vehicle in stock form
, and I no longer race at the dragstrip. I'd love to throw a 100whp at it, as I know the engine will handle it easily with good tuning, but the transfer case in these is not always holding up to the abuse, so I'm a little wary.
Good luck, and post some pics.
