What can I do to increase speed or horsepower?

[LordEnzo]

I just put 37s and a 3.5 lift. Mpg suffered by about 2 mpg. Power delivery is a little slower, but i personally don't feel its a huge loss. I was still able to go offroad with plenty of TORQUE to manuever and go up a steep incline. Eventually I will do a tuner, intake, and exhaust for the small boost (realistic gains of 20-40 hp in my experience, mostly too end). But as mine sits, extra power is NOT necessary and I'm am more than satisfied. As for ur options, what and most others have mentioned are what are available. Check aFe as well. Im on 4.10 gears. Second pic was not the steep incline..

OK, based on your post, I checked out the Livernois tuner. It shows greater HP and FT-LB gains than the Pulsar; what's more the gains are in the 2000-4500 RPM range, which is way better than what Pulsar does (4200-6200 RPM).

But I see a price of only $500, not $1300.

If I remember right, 500 just the tune. Then another 250-300 for the tuner. Correct me if I'm wrong..

Yeah, maybe you have to buy cable and unlocking, too? I have emailed them asking for clarification.

I assume your JT is under warranty. If so, you want the fully unlocked PCM to run THEIR tunes.
If you have to take the JT in, you want to remove THEIR tunes, go back to stock tune, and put the stock PCM in.
The PCM is the extra.

Did this to my Explorer Sport, you don't want them unlocking your PCM, you want to keep your stock PCM until warranty expires.

This was my approach. Not for the feint of heart, er, pocketbook!

I'm assuming that's not legal to drive on the street. Or, is there some way to make it legal?

Keep in mind that those numbers are on E85. That's not great to run in a vehicle not designed to have E85 run consistently. (Bad for the fuel system)

Actually, the tune you are talking about is for EITHER E85 OR 93 octane. There are multiple tunes in their tuner.

Why is the hemi easier to integrate?
LS fits much better

Supercharger, Turbo, or Hemi or LS swap. The choice is yours, depending on how much you want to spend.

Personally, once mine is paid for, it will be getting a 6.4 Hemi swap. I'm more of an LS fan (I'm not into buying 16 spark plugs at a time), but the Hemi integrates with the Jeep so much easier than the LS does.

not necessarily..

most injectors are are stainless these days so they wont corrode and fuel pumps are designed to have alcohol content.

the Livernois tuner supposedly has a flex fuel tune which means that the engine was e85 capable from the factory.

But the full power will only be on E85. You won't get the same numbers on 93

Some alcohol content, yes. But E85 is hydroscopic so it will draw in water and over time that will corrode lines if they're not intended to run on E85. Just because they make an E85 tune in no way means that Jeep made the system E85 capable. For some time it will likely be fine, but over time it can become a problem. I was in the Subaru world for a while so I've seen what it can do.

I agree with that.. What Im saying is since most fuels have some ethanol content (10%) manufacturers have started using corrosion resistant materials.

But also, Livernois cant just write a flex fuel tune on a car that doesnt have an ethanol sensor..

you either have to add it (like I did on my time attack car), or its there from the factory.

Livernois told me that the sensor is there from the factory on the jeep.
If that is in fact true, I wouldnt hesitate to run E85.
But the real question is why would you want to?
To drag race somebody?

I would much rather have 50lb/ft of torque down low that can run with 87.

Trade it in for an eco boost

I am not interested in E85. But the power/torque gains at lower RPMs with E10 (Livernois) sure look interesting.

Not sure I want to replace my PCM; that is what makes the Pulsar attractive. Plus it also offers some other non-tuning features like ESS control and speedo calibration. Decisions, decisions.

You can run E85 without an ethanol sensor, but only if you are specifically tuned for it and always run it. The only cars that have one as standard (that I know of) are flex fuel vehicles that can run whatever. The reason Jeep says not to run E85 is (I believe) because it does NOT have a sensor for it. I imagine the components can handle the alcohol content since standard gas can have 10-15% depending on where you live, I don't know how much of a difference there would be to run 85% vs the 15% from a materials standpoint.

The only benefit I can see outside of just wanting something that will get off the line quicker is when towing, but if I were doing that often enough to tune for it I wouldn't have a Gladiator for that job. I already have a car that will get off the line like a spanked ape, I don't need that in a Jeep
