2007 Jeep Grand Cherokee SRT-8 4dr SUV 4WD (6.1L 8cyl 5A)
All I can say is that this Jeep is not what I thought it to be. First off, when you punch the gas, the Jeep has this big delay and hesitation. Then it will take off, by that time the other guy is at least 3 car lengths a head of you. I just don't get it. This truck is to have 420 pony's. But it feels like it has half that. Its said to say this but Jeep needs to re-think things a little. I still have my 01 X5 4.4i. And I had my buddy race me with it, sure enough my old X5 beat me by a car length. I'm tellin you, they just don't build them like they used too. Even BMW has changed there stuff. I'm getting rid of this truck and picking up a Porsche Pepper. That turbo S is sick.
Engine bay, wide tires, rims, and exhaust position.
Tranny, hesitation, engine response. Everything else is small time. The major stuff is engine and tranny. Revamp my friends. Or Jeep you will be solf off again.
