I have recently purchased an '07 ram Hemi. Unfortunately I didn't realize that I needed to run 89 octane gas (so I ran regular for a couple of tanks). So I am still purging the regular gas. In the mean time, I replaced the stock exhaust by removing the 1st resonantor, new performance muffler. Now that I can hear the engine, I can tell it is not running right when cruising down the road at low RPM's, it sounds like it is flooded. When I step on it, it sounds ok, but I am pretty sure something is wrong. Any ideas? Is it possible the computer is confused by the gas and needs time to adjust? Thanks for the help!

Welcome, and it sounds like you're hearing MDS kicking in which will be much more noticeable after adding a performance exhaust. I doubt a couple of tanks of 87 octane would hurt ya. Congrats on the new truck!

Yep, agreed! sounds like MDS
hit your tow haul button and see if it still does it. My moms been running 87 octane in her 05 hemi durango since it was brand new and she hasn't had any problems with it. I wouldn't do it but you'll be ok.

Welcome aboard Mac's 07 Hemi - we're glad you joined us!
Most likely the MDS doing its thing is what you're hearing. Like Starchief_59 suggested, try disengaging O/D and see if you can still hear the noise. ______________________________________________________________________________ HTC.com web site HTC.com store HTC.com calendar HTC.com National map After smoking a pack a day for 30 years, I quit cold turkey.

Thanks guys!
Unfortunately, I still have this issue when OD is off. So it sounds like MDS is only active when in OD. Is it possible I caused this by removing the 1st resonator? In case you haven't noticed, I don't know much about this stuff, but I appreicate the help |

OD will still go into MDS. Turn tow haul on.
Look up MDS on youtube and let us know if that's what it is 1959 Buick Electra 4 Door Sedan 1959 Pontiac Star Chief 4 Door Hard Top 1976 W200 Dodge Power Wagon 383/ 727 4x4 1986 W100 Dodge Power Ram 318/ 4 speed 4x4 2007 Dodge Ram Single Cab Long Bed - almost no options except posi and HEMI! www.Pontiac-59.com |

You guys are good. When in tow/haul mode, I don't have the problem. I still wonder if I have another issue, when I step on it, it doesn't take off like I think it should.
Thanks for the help! |
