Actually 2 out of the three mods they did will drastically help the longevity of the motor given the added boost. The intercooler will help keep things cool on the intake side and the better flowing downpipes will allow the heat to escape quicker and allow for easier (quicker) spooling turbos. All of which I would suggest doing even if you don't tune... But the gains will be significantly better if you do tune.
I will probably do an intake and intercooler then wait for 3/4 of the warranty to expire before doing tune and exhaust.... Mostly to make sure they fixed the cam phaser bs... Definitely don't want to be stuck with that bill.
My only question would be why do you want or need more power? Forgive me for not understanding this but I just don't. I have owned SUVs since about 1999. Have had S10 Blazers and S15 Jimmy's, ramchargers, Durango's, Pathfinders, Isuzu Rodeo, Chevy Trailblazer, Expedition, Navigator, CJ5 Jeeps, and Grand Cherokees.
And not once did I have any desire to increase the power on any of these vehicles.
These newer vehicles have a god-awful amount of horsepower compared to what they did 15 or 20 years ago so I see even less reason.
Do your tow with it? Or do you want race the roads with it?
Do you get beside people in other cars and race them or try to out-muscle them which I have done all my life, but never, not once an SUV.
I will admit I have race people in my 70 CJ5 with 33 inch mud King tires and a 350 Chevy in it. It was damn fast for a Jeep. It did have Jaz racing seats with 5-point harnesses in it and was a powder-coated frame, fiberglass body, chromed-out engine show vehicle.
So if you tow something and need more power or want it just to feel better and have to give it last gas I can understand but I've never understood the desire of people to race around muscle people in a big 6000 pound SUV. I think they should go buy a performance car for that.
I do get into a people often and they're four door Chargers and Hondas and SUVs and such that want to have one car as a daily driver or a family truckster and wanted to also Dual Purpose as a race car performance. I don't believe in this. They can take their 0 to 60 2.6 second Jeep Tomahawk or Scalper or whatever they call it and stick it. Hey, scalper would be a good name for a fast vehicle though.
I'm one of those each vehicle has its purpose so have several. I have a pickup truck for when I want a truck. I hardly ever haul anything in an SUV. I just liked it. I always by 3rd row seating to get I've owned vehicles and never had anyone in the back seat. I'm just weird that way.
But I know, there are people that have diesel trucks that run sub-10 second quarter miles so there's something to interest everyone but I just don't understand why people with newer SUVs that already have lots of horsepower need or want more.
Please enlighten me. I will try not to be too judgmental. I probably won't succeed though.
