Installed in 5 minutes, greatly improves throttle response. You'd think it was mechanical linkage, just like old school! Installed with a 93 octane tune loaded, took lag out of the throttle response on a 2013 GT Mustang, Manual 6 speed, 3.73 gears.
Great Part!!!!!

I'm not a big time modder, CAIs, tunes, suspension stuff and the like. I thought about this mod a long time before taking the plunge. Anyone who hasn't done this is only hurting themselves. This is by far the best thing I've ever done to a fly by wire Mustang, this is my third, you really don't know how much your missing. It's like getting a different car, it's so much more responsive. It's probably not much faster, ET wise, but in normal driving it feels so much quicker and makes the driving experance miles better that stock. It's far and away the best mod I've ever done!!

I have a 2012 GT500. It is mostly stock, no tune or blower modifications. I wanted something that would solve the throttle lag so I bought the JMS unit. Holy Crap! I cannot say enough about the difference in acceleration after I installed this, its like a different car. Now the car is quick and fast! If you don't want to install a tune, but you are looking for bang for your buck, try this-You will not be disappointed! Very easy install and incredible results!

Warning!!! If this is all you read of this review, know this, there is NO manufacturer warranty, check JMS web site. LMR is the one of the best in every aspect. As for the Pedalmax, I received the first one, installed it, simple install, had problems with no throttle response at startup for a minute or two. Test drive was awesome! Does exactly what they say it does, gets rpm's in the low end up very fast, just what the car needed (2011 GT). When the temp outside reach 90 the unit started having problems on the start up (worse), no throttle response for a longer period. Contacted JMS directly. They were very quick to ship me another one and had me return mine to them. Installed the new one, no problems with throttle response but the new one is not as aggressive as the first one :(

I spent 2.5 months thinking about buying this mod, even after reading the rest of the positive reviews. I've had 6 mustangs, this is my 7th, a 2015 GT. Most of my previous mustangs have been older 5.0's of the 80's and 90s (Fox Body or SN95's). The throttle response of the new ones always seemed flat, or soft. After this mod, it really feels like a mustang and drives like it should. Better throttle response, feels much faster, and most of all it's more fun to drive. An equivalent I'd make is, similar to the difference from upgrading gears (in a foxbody), that's the difference this makes in the driving experience.

5 Stars   Good product. Very happy.

I bought the PedalMAX for my automatic EcoBoost and I have definitely noticed an increase in throttle response, it has been installed for about two weeks now and I haven't noticed any problems. I've a definite lead foot and my driving style compensated for the poor throttle response so I didn't notice this huge difference once it was installed. But it does make my car more fun to drive and it brings a smile to your face when you hit the gas and your car takes off with no hesitation. Additinally, the installation was beyond easy, even for a complete novice such as myself. The price is a bit much for what you get, at least on an automatic, but it isn't a purchase that I regret.
