Big increase to fun factor. Every time I step on the gas I have to let out a big ass grin Light presses of the throttle feel about the same so you don't have to worry that this will make normal driving difficult. When you press a bit harder though, you get up and go much faster!

I've played around with race mode and I think under most conditions it will be too jerky. That could be partially due to having a diesel -with the GDE tune, turbo lag has been significantly reduced, but there is still a brief pause when the turbo isn't spooled that makes the sudden acceleration in race mode [RED] too abrupt. That said, I can see it being fun to use if I'm using the paddle shifters and keeping RPMs up already so the turbo is ready to roll. But again this is just from having it on for an hour last night.

A suggestion to those planning to install - I found what I consider to be the ideal location to put the little switch that changes modes. I didn't want to have anything exposed. I saw a video on youtube where a guy stuck his under the steering wheel column (you feed the wire through the little leather flap under the column and out down by the pedals. You can fish it through w/out taking anything apart.) I took that one step better and stuck it under the steering wheel column on TOP of the lower trim, so even with your head under the column it's hidden - but still easily reachable while driving.

If you aren't sure what I mean touch the tip of you fingers (palm up) to the flap under the column, and bend your fingers. The should fold up into the column and come down on a flat surface inside the column trim... Now you can't see the mode it's on installed there but you should be able to tell easily from the feel of the pedal. And at night I suspect you'll see the glow of the button (red/green). And I did note that putting my phone's forward facing camera on and holding it in just the right spot could easily see it on the phone's screen...

Looking forward to some longer term testing! But so far happy for sure. Worth $300? Maybe? But if you can get past the price it's definitely more fun to drive!

Nice glad to hear you like it. Yeah I keep mine in red and unplugged the switch since il keep it in race mode permantley. It's just too much fun to not have it in that mode. Sacrificing gas but oh well

Re: Sprint booster

How is the install? On my WK I had to take bottom panel off or pedal assembly off. Can you get to it pretty easily without removing anything ? It looks like you can just from taking a quick glance at it.

You don't have to remove anything. Very easy install. The clip is about where the wires disappear up into the bottom "cover" under the dash, but it's very flimsy and can be pushed up or down as much as you need.

EDIT: You can see from this video what you should be looking for:

Thanks Kidd Funkadelic for the excellent review! Was hesitant about spending that kinda cash but after reading your review and all the other positive reviews I just ordered one. Got it for $289.00 (free shipping) from the Sprint Booster website. (What sold me is when you said light pressure is about the same) that was my biggest concern especially in stop and go traffic.

I checked out the video you're talking about, I like what you did so it's not visible.

Installing on V6 after ordering it now the suspense is killing me....LOL......I'll report back and give my feedback.

I think you'll be pretty happy!

Like I mentioned, I put mine on the top side of the trim from where you see it in the video (except rotated 90 degrees) so it's 100% hidden. Food for thought.

Re: Sprint booster

I'm on board Kidd Funk, I like to accelerate gently to save some gas, but when you put a little more gas, it gives you more acceleration. I installed mine visible, but out of the way and ran the wire around the side of the dash and down to the pedal. I'd like to be able to clearly see what setting it is on, and change it if I feel like I want to... Haven't so far though!

Re: Sprint booster

I have mine installed up under the dash of my 3.7 powered grand Cherokee. I just leave it in race. however I don't think it made a huge difference because of all the other mods I have, a few of which inherently improve throttle response. taking off from stopped I didn't notice an appreciable difference, but as I have stated, I have other mods which improved response. Now where I did notice a major improvement was in throttle response WHILE rolling. its significantly better in a roll to WOT scenario, this mod plus all the other will actually put me back in the seat.

however, I will be developing a throttle tune via HPtuners that will basically made the sprint booster an un-needed mod. because of the nature of drive by wire, even with the sprint booster in place, we still have a small percentage of throttle that's locked away from factory. meaning when you floor it, you're not actually at 100% throttle. I have the means to monitor throttle position at the throttle body vs pedal position.

stock without the sprint booster, we (at least in the WK crowd) see 76% throttle at WOT. meaning that even when the pedal is reading 100%, the throttle body is only open 76%.

now with the sprint booster in place, the WK see's between 83%-86% throttle at the throttle body with significantly reduced lag time. I think the increased throttle % is due to the sprint boosters "enhanced" signal from the pedal to the throttle body but the throttle restriction is still in place.

but this is the beauty of the drive by wire system, ITS TUNEABLE!

I currently run hptuners software and have been playing around with it along side of the sprint booster, so once I get my jeep back on the road again, ill be doing more testing. I have a feeling the sprint booster will only enhance the hp throttle settings

ehh, this article seems to be opinionated. however it does support what I said in my previous post to some degree. however, I think the sprint booster's effects are entirely vehicle dependent. I have found there is a slight appreciable improvement in response from a roll, which on a road course, a tenth or two improvement out of corners over a lap make a big difference in the long run. but I also make it clear I have other mods that also improve response to the point I feel the sprint booster is not necessary anymore. that goes back to it being vehicle dependent.


I think its more geared to stock vehicles vs ones that are modded like mine is. I do track mine as well both road course and drag strip.

it was a good read tho, not taking that away from your post

Not very favorable, in conclusion the author of the article pretty much says it's a waste of money. Reading the comments was even more interesting. I look at it this way if I don't like it I'll just return it within the 30 days!

Exactly. At the time I got mine I didn't have a means of tuning the drive by wire system itself. Now that I do, I'm not seeing the need for it as much
