GDE hot tune

Guys. I've had Keith's Eco tune for months. I just got the hot tune. All I can say is,wow. This is hot. It's almost hard to drive residential. If you have a choice get the hot tune. The mileage is about the same but the power is overwhelming. .

Sounds awesome! Does yours also not shift until 3k, even when driving slowly? Seems high, mine shifts at 2k under normal driving. Did you get the DPF delete also?

That HOT tune is like night and day compared with the econo tune. He did a great job on that! That is what I'm running also.

And you say the mileage is about the same as the eco tune? Some guys say you lose a lot with the hot tune. But if the hot tune will improve the mileage over stock then it is still worth it I think. Curious to hear what others have reported.

I have a hot-tune, and im not gentle on the throttle. I do a mix of highway and city driving, with a hard foot. I get 11.3 Litres/100kms.

The response and power are alot better with the tune. It is very throttle sensative now. It takes some time to get use to, driving style changes a lot.

Good Tune, worth every penny.

My initial test drive with the HOT tune was 20km city, 90km highway, light foot, speed limit yielded 9.8L/100km.

With my normal driving style and same city/hwy ratio I'm getting 10.7L/100km - WAY better than stock - plus I get to raise an eyebrow or two now and then lol

Ya that sounds pretty good for the driving conditions, mine is getting 9.1L/100 strictly highway, but I havent had the jeep in the summer yet. I wish you got both tunes for the price because its expensive ha.

I drove the Eco for 6 months then flashed to the Hot. Freaked me out a bit when it ran up to 3K before shifting to 2nd, but since them I've trained my right foot to control it better. First tank I dropped MPG about 5% - 2nd tank looks like the MPG will work out to the same as I was getting with Eco.

My wife does not like the Hot - it surges forward to much for her tastes. I keep the flash tool in the glove box so I can flash back to Eco when she's driving it (not frequently - this is My Jeep).

I agree the Hot is WAY better than the ECO. I only ran the ECO for about 3 weeks and found it still too laggy. The HOT almost breaks the tires loose with a simple Blip of the throttle. On paper it shows only a few more HP and LBS FT TQ, but in real world driving it feels much more powerful. The low end really comes to life! Boost spikes to around 24 psi then settles around 22 psi. Stock was around 20 psi, ECO tune was around 21 psi. Not much more boost but you sure feel the difference.

Definitely sounds like I'm going with Hot tune. So does everyone's shift at 3k under normal acceleration?

Mine doesn't, it seems to shift at lower rpm than stock with a feather foot. 3000 seems awfully high...

Mine does not ALWAYS do it. Seems to depend on throttle position. A blip or release of the pedal and it shifts.
