Question for you - does yours spin at 2800-2900 rpm at 75 mph on the highway? Drives me nuts to have mine running that high with all that torque starting so low with the tune in place. I keep thinking it's going to shift, it's going to shift... it's... crap.. it's not going to shift. Contemplating 3.23s to bring the revs down, coupled with 32" tires to get them down further... Can't imagine gear swapping is cheap though.

Only had mine for 5-6 weeks. Have the GDE tune, the OME lift, and tires in the garage waiting for me to have time to do mods and for TPMS sensors to come in... traveling consultant pays well, but is crap for having time at home to do anything fun.

I can't find anyone with a programmer that we can use to turn off the idiot lights for the tire pressure - have you had any luck or did you swap your sensors over to the pintlers? I ask because I bought 2 sets of wheels - one off-road and one on-road, and since we're hoping to move to WA state this summer, the stock rims will perhaps be repurposed to snow/studded tires. too much tpms swapping for me to stomach.

Maybe I just need to find some incriminating photos of a head mechanic at a Jeep dealership or something so I can gain access to their StarScan machine.

on your build. Very nice.
Yea it revs high...the bigger tires will drop the revs a little....I bought new TPMS for my Pintlers...I have had no issues with them at all.

So what do you both think of the GDE tune? What kind of numbers are you getting? Any options to specify? I know he does not do DPF delete, but anything else?

Thanks.

Get the tune. Don't think about it, just do it. They may have the Swirl Motor mod incorporated now - I'm thinking hard about going back and asking for it to be added to mine.

That Torque ... it is just amazing. full torque just off idle.. better acceleration, better HP, better fuel economy... getting 20 in town, 24-25 highway if I don't go the speed limit (75-80mph is just too high for the engine, I think)

assuming no correction on the speedometer, the rpm's drop, but only because you are going slower. i went to a marginally bigger tire 265/60/18, which is about an inch larger in diameter compared to stock and an indicated 100 km/h is actually 98 km/h.

glad you like the tune, i'm considering it as well, does the tune get rid of the hesitation when you need to accelerate hard from a stop? i thought i was going to get t-boned trying to pull out into traffic feeling like the jeep sat there for an eternity before it went.

I don't agree with your math there. Or you've worded it oddly.. Going from my stock tires to 32" tires increases diameter by 8%+, and decreases the revs to go a mile from 680 to 630. I can drive, using your example, 92kph on the speedometer, and be at an actual speed of 100kph. (until I get things recalibrated, anyway)
From the RPM perspective, installing larger tires drops the engine speed ~200rpm to maintain (TX) highway speeds. Not as much as I'd like, but I'll take what I can get.

From a dead stop, yes. Not much hesitation there any more, and quite a snappy 'get up and go' off the line. But taking your foot off to coast a ways, then deciding to stomp and accelerate still throws you into a momentary abyss as a) the computer figures out what gear to put you in and b) the turbo spools back up. THAT can't be corrected though, near as I can tell.

Scootr29,
You have an awesome Jeep. I really enjoy the work you have done. Now much mpg did you loose with the large tires and lift? I am a big fan of the DuraTracs, I have them on my F250. I wish they made 245/70/17 in a C rating. I would love to do this to my wife’s Jeep, but she would kill me. Thanks.

you're right, i had that backwards..thanks for pointing it out.

the lag i was referring to is computer related i think because even with turbo lag, the vehicle should at least start moving when you get on the peddle.

I'm a numbers nerd. I can't help myself.

The tune definitely makes a real difference at launch "from the line". But the tune doesn't change the TCM, so there's still a moment of when you're coasting along then punch it. Some is the TCM, some is the spinning up of the turbo.

Finally got my Cibie H1 high beams installed.....got a plug and play harness from rallyelights.com....it is a little pricey but it is done right. The harness allows me to include the cibies when I hit my high beams....lots of candle power now......

Also installed a set of Phillips HIR Low Beam and High Beam bulbs...these are direct replacements after you file or dremel down the top tab. Took me about 5 minutes for all the bulbs to get them to fit. I used a dremel cutting tool and file. These bulbs are probably the best direct OEM replacement bulb on the market...I got them from rallylights.com

I also bought a set of Bosch 100 compact lights to replace the OEM fog lights.

Update on the 100s.....actually the 100s fit nicely into the OEM plastic housing. I drilled a hole in the top of the plastic housing and attached the fog light to that using the supplied bolt and locking nut.

I have ordered some connectors to make it look OEM.....
