2008 3.8 throttle enhancer: which is best?
- Thread starter John Cooper
- Start date
I have a Pedal Commander been using it for 5 years, don't know how it compares to others.
Of course he sells his brand so he needs to make his sound better, does he sell his brand for a Jeep?
They're all basically garbage and every car I've driven with one installed essentially feels just like stock with a marginally different throttle response curve. Personally, a 1:1 ratio is the most logical for 99.9% of driving and is easy to predict. Unfortunately, in the age of "lazy transmission" programming (under the guise of "fuel economy"), poor gearing ratios, and drive-by-wire, you just need to get used to your shift points and learn to manipulate the throttle accordingly.
In the case of the 3.8L, it's a minivan engine pushing a brick down the road. If you aren't regeared, start there...
Yes, of course it's available for Jeeps.
If you watched the whole video, he's not just selling his brand, he's settling a fight that Pedal Commander started with actual evidence of how unsafe they are.
Whoever fixed my title, thanks!!!
Stupid phone wouldn't let me edit at work this morning!!!!
I'm not looking for more power, just throttle response.
I do have plans to regear in the future, probably in the next year.

The best throttle response I got on my 2008 JKU X was to go from 3.21 to 4.10 gearing on 33" tires. That woke it up.
The pedal control modules do little or nothing. If you want to improve throttle response, start with tire size and gear ratio. Or (and nobody will be surprised when I say this) a V8 swap.
Our recent experiences are:
2011 JKUR with 3.8L and 4:10 differential gears and an A4 and 35" tires. It feels sluggish. But it's responsive enough for my wife, so she drives it.
2013 JKUR with 3.6L, a few engine mods (CAI, exhaust, 93 octane tune) up from 285 to 300HP, 4.10 gears and a M6 with 35's. It's marginal, especially on the highway and mountain passes.
a 2023 JLUR with the 392 Hemi with a bit of engine work (mostly a premium tune) making 500HP, 3.73 gears, an A8, and 37's. The math says I'd be better with 4.88 or 5.13 gears, but I don't see that happening unless I eventually go up to 40's. As it sits, it will spin all 4 on a hard launch. More Power!!!!! is the answer to most performance issues.

Even then it was still grossly undergeared , especially if it had a 42RLE
Im probably going to go to 4.88 with the 42rle. That's my next big thing to do to both the JKU and the TJ will get 5.38 when I do it.
