Re: Sprint booster

Drove to Perry, about a 36 mile round trip. Kept it in the stock position on the way down. Put it in the Green position for the return trip. I'm impressed. The RPMs certainly climbed more quickly. I didn't stomp on it as my wife of 51 years was riding shotgun. When cruising, no difference from stock but the quicker response is lurking on the underside of the throttle pedal.

Big RED tomorrow for at least an 80 mile round trip. Most of it will be on I75 and the Smokies will be on high alert so I'll have to be on high alert too. My Passport, the Waze app, and my CB will get a workout I'm sure.

Re: Sprint booster

Going to order the Pedal Box kit due to the extra adjustability between modes. Amazon has them on for ~260$cdn shipped.

With Pedal Box you have 6 adjustment levels between Sport, Sport+, City and Off. 3 up and 3down to fine tune it to your taste.

Only downside is the controller doesn't disconnect as in the Sprint Booster.

Minimal cost difference. Sprint Booster is 50$ more expensive before shipping.

Re: Sprint booster

I turned the Red light on and drove sedately the 4 miles to the interstate. Clear right lane before and behind me so I nailed it. Oh yeah! The RPMs climbed quicker than before and the Hemi sang a sweet tune. I leveled off at 65 MPH and cruised on. With ECO activated, the MPGs increased by 10ths every few miles. This mod is the best of two worlds as it doesn't affect normal driving but when you want quicker/sooner acceleration, just press down and hold on but when you want the mileage the engine is capable of delivering, just rest your right shoe sole lightly on the pedal.

Re: Sprint booster

I went back to stock mode and it's embarrassing how much lag is built into these vehicles. That has to kill more people than the shifter.

Safety concerns- definitely the reason why I installed a sprint booster on mine. Is it way more fun to drive? Damn right it is, but that's just a nice plus to it 😀

Have you disconnected ECO drive before, if so, how much difference is the sprint booster from disconnected ECO drive?

Since I disconnected the ECO drive my Jeep responds way faster, but I also have K&N air filter and straight pipe so that helps also

Re: Sprint booster

Sweed, I thought about doing that very thing earlier and will do so tomorrow. I think it would help when cruising. Thanks for asking.

And, my only other mod is a drop-in, AFE dry air filter.

Re: Sprint booster

I put a Sprint Booster on mine 2011 3.6l Limited last weekend.
ABSOLUTELY LOVE IT!
Before I bought it I read all I could about it and quite a few white papers said it would both help and was voodoo.
The one that really caught my eye was one written by a tester that put one on a Mercedes and connected instrumentation both before and after it in the circuit.
The paper was an interesting technical read, but pointed out something that MB does that I'm curious about.
The author (Dick Bipes) says that the MB ECM has two basic modes, quiet driver and sporty driver, in quiet driver mode the ECM gives a 50% pedal movement 40% of throttle opening, and in sporty mode gives 80% of throttle opening.
There is no difference above 90% pedal position, it just goes.
The ECM switches mode based on driving and gives no indication it is doing it.
SO the Sprint Booster, by recurving the pedal voltage feed to the ECM forces the ECM back into Sporty Mode immediately.
I wonder if our ECM software, since it was originally a MB design, has this "feature".

Anyway I love it, run it in green mode all the time, and will never give it back.

Re: Sprint booster

I think green mode is best. Red can be a little choppy.
