I have noticed a big difference in my Jeep. The lag in acceleration is gone and I have picked up a couple of MPGs. The biggest thing I would recommend is Disconnect your battery before you start. I followed the instructions and I had a problem with the engine running up to 3000 RPMs. I contacted aFe and they said they had never heard of this happening, but never contacted me back. A friend suggested to reset the computer by disconnecting the battery. When I did this the Sprint Booster worked perfectly.

I had high hopes for this but left somewhat disappointed. 1st time installing it I got the Check Engine light and rev to 3000rpm. Went back to normal setup and light went off. Tried it again and it worked, Great! I had just installed the AFE CAI as well to help with this. To say I feel a lot of difference, no. Can I feel some, yes. Can I tell the difference between Race 1 and Race 9? No. I have had this for 4 months ago and have had the Check Engine light come on about 6 times now, 2 times it put my car into limp mode. Shut the car off and turn back on but engine light is on but will run normal. After a few hours the check engine light goes off and back to normal for a few weeks until it happens again. I will see what AFE has to say about this but who knows.

Installed on ‘15 Jeep JK.This is the V3 version. Works as advertised. No more lag when first stepping on accelerator. Set mine at race level 9.Note: connector on pedal is a little far under dash so takes some patience to disconnect and install.

the lag during acceleration is gone use now when cruising the green mode set to 5 works flawless, offroad in the dunes red setting at 6 for more extra punch climbing up.but fuel economy stays the same, I do not see any difference to before.

Been extremely happy with this item. Bought to try to address the dead spot around 35-45mph, and this does the trick. Very smooth acceleration, and I think is a good compromise to get back acceleration after larger tires at a fraction the cost of regearing. I have found the middle setting yields better MPG than stock setting as well by 1-1.5mpg. With my 3.73 gears, 35" tires and this I am generally combined driving getting 17.1 to 17.6. There is no way a regearing pays for itself in better mpg, and 3.73 gears are a great set for all around Jeep use, so adding this seems to be a great alternative. Even towing 12x6 a U-Haul trailer I averaged 15.1mpg at 65-67mph on a level trip.

I bought my sprint booster from an aftermarket retailer for my Mercedes Benz CLK 500. My CLK 500 acts more aggressive and I can feel the increased torque.. I am very pleased with this product. This is a must-have. I would recommend this product to anyone.

If I could upgrade one thing, this would be it. Wish I bought it sooner. Difference in acceleration is night and day. Pedal lock feature is a bonus. For the minimalist, no bulky boxes/controllers. Made in EU [premium quality].Quick and easy install [2017 Jeep Wrangler JK 2 door 20x33 all terrain tires]. Improved shift points on automatic transmission; no hesitation on upshifts and downshifts, smoother shifts overall.

Very easy to install and definitely adds more response to the factory pedal
