I am not disagreeing with you at all. I realize there are a lot of physical differences between the two. It is however possible to get 390 Horsepower and 407 Foot Pounds out of the engine on the Jeep using the in place equipment with a program change.

The Conversation was more about them not offering it in this particular version even though likely Chrysler doesn't actually have to change much to do this. Mind you the Durango Police truck Milous just posted in the 2014 Durango thread is exactly the type of vehicle I have seen them run these types of programs in.

Impala Police cars ran a different engine program with much higher horsepower and no speed limiters. They never changed anything on the engine to make this happen. However due to changes in emissions standards, this type of modding by the manufacturers has gone away mostly.

No truth in that at all. Police cars tend to run slower due to added weight. Its been tested in magazines for years. Police cars have not had special engines since the early 70's. The only thing different is maybe the speed limiter removed. The Ram does not make 390 because of a different tune. The tune maybe different because the engine components are different, but putting a "Ram tune" on a Jeep will do nothing.

I suggest you don't want to argue this with me. I was in possession and have tested Police Car software from a manufacturer. It has been a little over 10 years but not 40.

I agree with the weight and testing, more current stuff is slower..... anyway off topic I am sorry I brought it up.

Either way, there is no "Ram tune". Different manifolds for I/E. The tune on the Ram truck is specific for those parts on the identical Hemi engine. Put a higher hood to clear the intake and run some headers through your wheel wells and then the jeep will perform better and make the 390.

Lots of fun comments here. My other ride is a '12 maxima. It rocks my v6 14 overland and I just today beat on a 12 or 13 hemi jgc. Honestly, if it wasn't for the performance (compared to the TRUCK, ) I wouldn't drive it at all.... I love the ride in the jeep (even with uconnect sucking the life outta me).

Also, while comparing apples to apricots, my 92 Acura legend beat all of my other cars to include a 6cyl 89 camaro, tuned civic, and my current maxima and jgc.

I want more from both, but don't regret getting v6 over hemi (upfront cost, fuel economy, and little mentioned fuel required).

I'm currently mulling over CAI for both maxima and Jeep but not sure about drop ins and difference between oil and dry.

Any thoughts?

The new Exploder cop version was on Jay Leno's Garage. Different motor than what the general public gets.

Thats a first in a long time, but in reality its just the engine from the Edge Sport. No special police tune. Its actually down 5 Hp from the Edge and you can still get a more powerful engine in the Explorer. So its not really a special, more powerful, one off police engine. Like I said, that has not been done since the early 70's.

Re: Got demolished by a Ford Explorer Sport

Most government type vehicles run federal emissions vs MA or CA versions. Not sure about power ratings

Sounds like it was running CA emissions since it was down on power to the Edge. Wouldn't be surprised if this eventually becomes the standard Explorer engine too.
