Calling me out? I didn't realize we were breakdancing. Unless you can comment about the driving characteristics between the tunes just keep your butthurt comments to yourself and stop clogging up the thread.

There isn't a huge difference in drivability, power on the dyno or times at the dragstrip between the tunes from HemiFever or DiabloSport. At WOT, the HemiFever tune seems to shift harder between the gears but it's a 93 octane tune and there is a little bit more activity with the knock sensors. The DiabloSport tune is setup for 91 octane and because I use 93 octane gasoline anyways there is less activity from the knock sensors vs. the HemiFever tune. Like I said before on my Jeep either tune would work and I was happy with the service I got from HemiFever via email. I had no need to call Diablo so I can't comment on their customer service.

Driving around town I can't feel a difference between the tunes neither one feels better in terms of throttle response, smoothness or drivability. So I continue to use the DiabloSport 91 octane tune because the knock sensors are less active.

I hope this helps

I use the 89 Hemitune (hard to get 93 octane gas where I live and it wasn't any noticble diffeence between 89 and 93) and to me it's a huge difference in throttle response between Diablosport and Hemifever.

Since this thread I had switch back to feel it again and I couldn't drive home fast enough to switch back to Hemifever, lol! Sean from Hemifever said he gave my tune a little extra throttle response so maybe you should ask for that as well.

The only complain I have is that I wish mine had higher top speed, my Jeep tops out at 130-140 now, which as a lot better than the stupid stock 110, but, more wants more

For me it's Hemifever all day!

That's the same I'm using as well, but I got mine from Hemifever, so mine had the custom tune included in the price.

You mentioned HemiFever gave you a little bit more throttle response. Did you ask him exactly what he changes to achieve better throttle response? Currently, I use the Pedal Commander which I like very much because of the 13 different modes of operation, so I'm very happy with the throttle response I currently have now.

Maybe it's me but I can't see how one tune can be a whole lot better than another when a vehicle is basically stock. You need four things to make power and they are Air, Fuel, Spark and Compression. Tunes aren't adding any extra air or compression so that leaves fuel and spark. Adding more fuel doesn't add HP unless there's an substantial increase in airflow. More fuel may be added for detonation or activity from knock sensors and that will net a gain in performance due to less total timing being retarded. But the million dollar question is how much performance are you gaining for less timing being retarded? You need to dyno test to answer that one.

Adding more spark will net an increase in HP but you're limited in how much you can add. There will be cases where more spark advance increases knock and timing will be retarded. So I see tuners changing spark and fuel tables to achieve more HP and TQ but the question remains is there that much of a difference between tunes on a basically stock vehicle? Granted, they also make changes to transmission shift points but that's not adding more HP or TQ.

I decided to seek the advice from another tuner and see if they are willing to do a custom tune for my Jeep and then I'll compare them against the other tunes I have. I'll report my findings when I'm done.

Thanks
Michael Plummer

Re: HemiFever vs. DiabloSport tunes

Nice comparison. I can't speak for the 14+ models but for my 2011 with the 5 speed, the Hemifever is a must. He modifies the torque management, and you definitely feel the difference in the transmission with shift points and the firmness. Not sure about how much hp gains you get over stock, like you said there's not much to be gained over a stock naturally aspirated motor, but to me the Hemifever is worth it for the transmission tune alone. It definitely feels faster for those with the 5/6speed trans than the diablo tunes.

No I did not ask him what he did, that was just what Sean told me he did, I said I wanted a reliable race car

I have the k&n air filter and muffler delete as well, I felt and big difference after just doing that, and when I got the DiabloSport/Hemifever tune it actually made my car pretty fun!

I am curious about the Pedal Commander.

Btw what's your top speed?

Sweed,
I'm not doubting what you experienced on your Jeep, if it feels quicker and faster it probably is quicker and faster. As nickbencze said above "He modifies the torque management, and you definitely feel the difference in the transmission with shift points and the firmness."
. I believe but I'm not 100% sure he modified the torque management but I will send HemiFever an email and ask about the differences between my (2) 93 octane tunes.

As far as top speed, I don't know. We removed the speed limiter and so far I had the Jeep up to 108MPH on the New Jersey Turnpike.

Thanks
Michael Plummer

You used the intune as opposed to the Trinity?

Should have the same type of programming, wouldn't you think?
