In no way in hell would I ever buy a vehicle 1-2 years old. Still way too much devaluation going to happen.
My 2011 was listed as $58,677 on the window sticker. Original owner probably paid $55k out the door, assuming they got a good deal.
I bought it 3 years old for $26,500 out the door.
So someone lost over 50% of the vehicles value in just 3 years.
I just looked up KBB and it's still values around $27k after a year of ownership.
According to the numbers claimed by the manufacturers of my bolt ons I should be around 40-50hp increase. Even modestly / realistically I've got to be 30more horsepower with these add ons ... That should definitely be noticeable.
I don't expect to have a race car or even remotely close to an SRT which is geared for speed. But damn this thing isn't what I expected coming from ZJ and WJ.
I'll post some acceleration videos to see if she is really about as expected or if she maybe has a problem.
This is the whole idea manufacturers of these bolt on products have in mind when marketing. They are counting on dominance of the placebo effect on the majority of their customers. They count on the customers that buy their products to not have access to a dyno either before, or after the mods and count purely on the susceptible minds of the users that buy them. They spent good money on the bolt ons. In their minds, the mods HAVE to make the vehicle perform better. The NOISE alone from an exhaust mod gives the illusion of astonishing performace to those who possess minds susceptible to the power of suggestion. A cold air intake is far louder than the stock intake baffle system, so, it MUST be performing better. I now have to use 93 octane, according to my Diablo Tuner, after programming, so it OBVIOUSLY has to be performing better because now I have to spend more on fuel.
I have a 2015 Laredo 3.6.
I want to install dual exhaust on it (has single on right rear now) because it will sound a little better and LOOK cool. I like symmetry. I am not doing this for performance. I am into aesthetics only.
I've gotten my speed need out of my system with my last vehicle. SRT8 300.
Anywho, your 2011 hemi, as I can tell you've figured out on your own, was probably running near it's peak maximum with it's stock intake, exhaust and stock programming. So there wasn't much room for improvement without breaking open the engine with bigger cam, injectors and polished heads or whatever.
I'm sorry you spent all that cash for no tangible gains. That sucks.
Supercharging, like a few gents mentioned here, is the only way to go for substantial horsepower and torque gains. That is where you will find that getting sucked into your seat experience.
The only 3 bolt on mods that potentially have any HP increase are the things that you did. But it depends heavily on how well the original setup was designed and if there is any room for improvement.
