Pretty sure the tunes are identical between the two

Yes, Trinity just have more options and is a little more expensive, that was the reason I choose Intune over Trinity.

Re: HemiFever vs. DiabloSport tunes

I loved my 5.7 and read this entire thread. I went to the dealership for a door lock actuator repair and test drove an SRT while waiting. Two days later I traded in my 11' and left in an SRT. I can not tell you how happy I've been in it and the performance is amazing. I know not everyone wants or can afford SRT payments bc I was in that same boat. Imo, if you're not dropping a blower or turbo on it, the 5.7 is going to be around a 14 sec performer and high 13's on nitrous. I wanted to believe in my 5.7 Hemi, but the 6.4 has won me over..
So please don't test drive an SRT if you have the self discipline.....
MP, we have the same taste in cars and if you want the power of that Stang in a Jeep, SRT is the way to go. I loved my 94 Cobra and dumped over $100K in it during my 14 year ownership and loved the power. This SRT gives me that same Stang dominante power on the road. Google up 94SC50 or 94Turbo50 and my SRT is on ig @SRTNinja

You're correct about the 14 sec time slip and I have no intentions of putting a power adder on this vehicle. One of my objectives with this 5.7L Jeep was to try some of the more popular bolt-ons and document the results with dyno and 1/4 mile runs. It's always better to have data vs. playing the guessing game. Hopefully the data I post gives somebody an idea on what they can expect.

I did test drive (2) SRT Jeeps. One was a 2014 and the other 2015 basically the same vehicle. Yes, the performance difference in terms of handling, braking and power is obviously better than my 5.7L Overland but I wasn't blown away.

Things I didn't like about the Jeep SRT.
1. Suspension doesn't react fast enough on bumps and changes in the road.
2. Brakes didn't seem to hold up well. They fade after repeated stops most likely due to the vehicle's weight.
3. Not 100% sure if the performance upgrades are worth the extra cost (to me... still trying to decide). But the itch for a 2014-2015 Jeep SRT is still there despite the things I don't like.

BTW,
Your old Mustang looked like a fun and fast car and I'm happy to hear the Jeep has filled that void for you. Not looking to replace my Mustang, just not sure if there's room for two toys just yet.

Thank you
Michael Plummer

Re: HemiFever vs. DiabloSport tunes

Yeah bro, it's not everyone's cup of tea. I resisted a few years bc I needed 4x4 and finally this year I was able to make the switch.
The mods are not cheap either for the SRT. It's great you're getting all this data bc it will helps a lot of others for sure. I actually ended up on this thread from a Google search for DiabloSport tunes.

Re: HemiFever vs. DiabloSport tunes

My 2 cents. I ordered the Diablosport from Hemifever mainly because I tow a small travel trailer. I also wanted to correct the tire size since I'm running 32" tires. When I programmed my Jeep with the canned 87 tune I only noticed a very small improvement. I attribute that to the tire size correction which corrected the gear hunting.

When I installed the HF 87 tune, I definitely felt a huge difference. It came alive. A few weeks later and after runnig 3 tanks of 91 octane fuel, I installed what I thought was the HF 91 tune and it felt slower than the HF 87 tune. I was like WTF!

It was later that I noticed I mistakenly had installed the canned 91 tune instead of the HF 91 tune.

Boy, what a difference! My Jeep feels fast (ish,) and picks up with ease. Much better than the HF 87 tune.

* I actually beat a dude in a Honda Accord coupe 4 cyl from 0 to 80. So far I am pretty satisfied with my Hemifever tune. If I wanted faster, I would drive my XJR.

*Disclaimer: Race conducted in a closed and controlled environment.

Re: HemiFever vs. DiabloSport tunes

I ran the 87 Diablo tune this weekend. I think it felt the same as the 91 but maybe a little more sluggish. No change in mpg. I ran 91 gas because I forgot I changed the tune. I would have to say i couldn't notice anything noticeable between the two

The same for me, no noticeable change between the 2.

Big change in my Hemifever 89 tune from the Diablo tunes though.

Re: HemiFever vs. DiabloSport tunes

Anyone know if the Diablo dcx is the same as the intune? I got a email from diablosport saying there is new update including throttle booster options. That would be nice.

Not trying take anything away from what you said. However, this statement is not 100% accurate. Out of the intake and exhaust parts, the stock exhaust manifolds will be the biggest thing since the cats/catback are fairly efficient. Replacin them with srt manifolds or even long tubes will make a very large improvement.

Of course.....a slightly larger throttle body will get some small gains from mid range up

Any data to show HP increase with long tubes or larger throttle body?

I have, like you, track times to back it bro. I picked up 3 tenths thru the 8th swapping out the logs for tube headers. Plus im currently making 30rwhp and 40rwtq over stock on my jeep (granted a 3.7) but its proof of concept that they work
