3.6 Engine - Now I understand the power issue

[legacy_etu]

I wish Jeep would use the same tune as the RAM 1500 and bump the power to 305HP for the 3.6.
They could offer a DirectConnection Stage 1 tuning kit for the 3.6.

Right? Exactly…. I mean a little tweak to show they’re still trying to give us something and answer our complaints would be appreciated.

You should have seen us coming back home when my wife insisted I pass everything in sight - 85+ with ease, look up the winds we had with that big Iowa derecho a couple of years or so back. You have to let it run where it wants to run, don't baby it. If it drops a couple of gears and winds up - LET IT.

Exactly.

End of the day Jeep does what a Jeep is meant to do, if you want it to do something else then modify your car or purchase a different car for your "Wants" - to the ppl who complain.

I wish it worked like that. Plenty of horror stories about those that use additives still end up with failed cp4s. I can't say I religiously use an additive, but I can say that I fill my fuel filter with it. I believe, never run low on fuel and be sure to prime the filter head after a filter change. One bad batch of fuel is almost a sure way to cause early cp4 failures and that is out of our control. Even at a reputable station.

My understanding is that running low on fuel and getting air pockets is the "unofficial" leading cause of CP4 failures for the Gladi. Lubricity is still a concern which is why running an additive is important, but its the design of the pump that causes issues because internal components basically rely on the presence of fuel to stay in place and in tolerance. When fuel isn't present these parts shift ever so slightly and bind up or cause excessive wear which eventually leads to binding up.

And then bitch about it running too hot. Yeah, that's exactly what would happen.

There's really very very few who complain - but complaints are always louder than those who say they are satisfied.

I guess some haven't read, or choose to kick logic and science out of it - COOLING.
These were tuned as they are due to the huge difference between skinny front of a Jeep compared to a fat full-sized truck with a large cooling area..
These were a bitch to keep cool and meet the towing and payload as it is, and you want to generate more heat?

Ok, ill play.... you take your 3.6 rubicon, ill take my 3.0 rubicon.... we are allowed the same two modifications, say a 4" lift and 37's .... then we drive 500 miles to go wheeling in even an easy trail in Moab..
which of us will complain about power?

So now to fit your opinion, you move the goal posts - move them out another 100 yards.
You are taking it outside of typical, to the edge with pretty large mods.
On the other hand, many dozens do it - without issue.
People are doing it, just fine. Some even forum members.

OK, let's play that game - can your little diesel tow 10,000 pounds in hills - and not overheat?
Gee, the diesel must be an inferior engine.

Well said. People want to take it to extremes, have problems, then gripe about it. They are modifying it or using it beyond intent.
I can't tow 8,000 pounds at 95 mph - the Jeep must be a crap vehicle.
I can't add hundreds of pounds of weight, massive big tires with huge increases of rolling resistance and weight and still drive 100 mph - it's a crap vehicle, crap engine.

Jeeps are fun to drive as are quick vehicles. Having a quick Jeep is the best of both worlds.

People who complain about these maybe forget about the I6 powered Jeeps of the 1970s...........
As much as I love the 258, it was time for it to go.
The 4.0 - very amazing, and I still love it in my car, but time for it to go in general.
The Jeep Gladiator is a Swiss Army Knife - and you don't build a house with that knife - you get the proper tools for each job.

I didn't move the goalpost, I just did what most people do. Add larger tires. Your 3.6 doesn't have the power to twist them without regearing. Whereas the diesel doesn't need reged, because it has the power.... and I'll tow with my diesel versus the gas, there's several videos doing a comparison, and the diesel does just fine..... look, I get it.You bought the 3.6 so you feel incumbent on defending it, i upgraded Because I know the limitations of the 3.6.... and just for giggles in an OEM configuration, I'll race any 3.6 with my 3.0 from a standing start, IF YOU'VE EVER DRIVEN THE DIESEL, YOU'LL UNDERSTAND

I also wish the Jeep had more power, but I test drove it's 2025 competition and it's the most powerful "feeling" option. I know the turbos claim more peak power, but I can only guess peak power is at redline, because in a normal drive they all felt weak.

Gee, should take you up on that....................

Looks to me that on average, a 3.6 Jeep would win.

This is so much horse hockey its laughable. I ran 37” tires on my 2014 JK with 4.10 gears until I bought my Gladiator in January, and never felt I needed a gear change. I run the same 37” MT AT tires on my Gladiator and don’t see a reason for gear change.

I’ve posted elsewhere that I swap gears for folks in my shop, and have done one Gladiator with 5:38 gears for towing, so I can swap my own gears for the cost of parts and a Saturday’s worth of work…not happening anytime soon….

LOL, I was beating 3.6 in Jeeps and cars with ease..... in stock trim the 3.0 JLU and JT are fast.... I have practical experiance with this so I couldn't care what you say you found,

Putting in 4.88s is the best mod I ever did.
