It's nice to know someone has a fix. It sucks that Ram doesn't and this thing costs $329. Doubt I'll buy it for that price. Heck I coulda bought a B&M performance vacuum modulator, done a serious tune on my Holley and had a 1/4 keg of beer for that $ back in the day.

Ive noticed it a bit too with my new '12 sport. I just figured it has to do with break in period since I only have 890 miles on it in the 3 weeks ive owned it. I also read over at ************** that the break in period on these trucks can be anywhere between 5-7000 miles. My dealer laughed and said no, break in period on new cars/trucks now a days is about 1200 miles and then I can push it how I want. I have yet to floor it off a light, or attempt any "racing" in a truck, to see how bad this lag is, other then just gently starting from a green light. That and I dont want to waste 15mpg off my DTE by punching it off a light . I have the 5.7l hemi

Yeah Torque management has alot to do with lag plus the POS outdated stock coverter.

No. I have a Long Horn and they haven't come out with one yet that will work with adjustable pedals. If they do I will buy. I've heard great things about it.

Yeah, I have VERY low miles (615 after 2 months) I live on the tip of Long Island and everything is 1.5 miles away! I have also yet to mash it from a dead stop or race the truck. But I read in the manual that after 300 miles, "brief full throttle acceleration at legal-HAH- highway speeds is desirable for a good break-in" So thats what I did, and thats when I noticed it.

I just bought a 2012 Dodge Ram Laramie 1500 3 weeks ago. I have 5000 kilometres on it (3100 miles). The throttle lag drives me absolutely crazy. It is worse coming out of ECO mode. I love my truck but I didn't buy a 390HP Hemi for it to drive like a station wagon.

Wish it did drive like my station wagon.

Would be interested to see if this gizmo cures anyones lagging issue, but I have my doubts....in their FAQ section it says :

"Sprint Booster modifies the signal between the accelerator pedal module and the electronic throttle body. This modified signal forces the throttle body to open 'more' than the stock signal at a given pedal position. In effect, the idle-to-full-throttle pedal travel is reduced. This makes your car 'feel' more powerful because a given pedal input produces greater throttle opening. This is especially evident in the low to mid rpm range where most cars spend their time on the street. Sprint Booster simply modifies the throttle signal between the accelerator pedal and the throttle body. Big deal right? Keep in mind, this is the same concept as the 'throttle pulley' modification on cable based throttle systems - which was very popular in it's time. It doesn't add horsepower, but makes the throttle more sensitive and makes the car 'feel' faster."


Since it seems that our complaint here is of full throttle lag...ie we mash the pedal and there is a lag.....I cant see how this gizmo would help. The throttle blades cant be open any more than full open. This gizmo might help in part-throttle situations, but then you can do it yourself by giving it more throttle.


I think another poster had it right when he said it is due to overly agressive torque management and maybe torque converter.


Just my two cents,.

It's not just a Dodge thing, all make that utilize the "drive by wire" throttle have this same issue, although the factory does not consider this an issue, in fact the vehicles are programmed this way. Why, do you ask, it is so that there is a better chance the vehicle will comply with the CAFE standards that all manufactures are required to maintain. They can make the vehicle scream at the slightest touch of the "Go Pedal" but NONE of the vehicles would come close to the MPG standards that are Federally Mandated. Now if YOU modify the vehicle to operate "as it should" and your MPG suffers well then it is YOUR fault, not the factory. They use a delayed throttle and torque management (reduced fuel delivery + reduced throttle position + torque converter lock-up control) to keep the MPG up. My ex-Chevy did it, any newer Ford rental car I've ever beat the piss out of did it, my R/T Charger does it, my 3500 Cummins not so much. YOU can program it out no problem, but you could suffer lower MPG...mainly cuz your right foot will be happy
