My 08' ram sputters usually around 50-60km/h but only when I feather the throttle, what's causing that?

 

Welcome to the forum. If it has the 5.7L Hemi, that is the MDS system dropping 4 cylinders under light load to increase fuel economy. It will do it in most light throttle conditions, it's just not always noticeable. If you watch the tach, it will usually go up a couple hundred of rpm when it engages.

 

Thnx for the intel! I wasn't aware that the MDS system was put into the '08 rams, and yes It is the 5.7l hemi

 

Is it normal that it Kinda sounds like crap when MDS kicks in?

 

Yep, especially with aftermarket exhaust.

 

Right on! Well that's relieving, cause I was thinking I might have to do spark plugs, and they were done 40000kms ago, and didn't know what else it could be, was also thinking maybe a fouled injector/s. Is there a way to delete the MDS?

 

Diablosport has a thing that plugs into the diagnostic port that turns it off. I have one of their tuners that adds power and has the option to turn it off, depending on how much you want to spend, The free way is to push the button on the end of the shifter. when in tow/haul mold and OD off, it disables the MDS, but it will delay the 2-3 and 3-4 gear shifts a bit.

 

Interesting, how much is that diablo sport tuner, and how much power did it add for you?

 

I've had it since 08. I'm thinking around $250 maybe? I'm sure they are a bit more now..On the 08 it's good for about 25 rear wheel HP on 93 octane. It makes the shifts much firmer at hard throttle and raises the top speed limiter from around 105 to over 155. There are other things that you can adjust as well. I have been really satisfied with mine. You can check them out here. www.diablosport.com

 

Thnx appreciate it!
