Re: 08 hemi

Same thing on my 07 5.7...After putting an exhaust on it didn't fix the sound at all. Then I just put an intake on and it's still there. Even switched to synthetic oil with no change either. From the guys here who used the Predator to disable the 4cyl mode, does it get rid of the tick completely and does it run better?

Re: 08 hemi

The tick is a different thing. that is just there (unfortunately) When the mds kicks in n out mine does a miss/stumble/"shudder" thing. i've heard some say there are flashes that can fix or improve this, but my dealer said my truck didnt have any (he looked up my vehicle in his computer)
It's been said often that changing the exhaust can make it worse esspecially if you loose the resonator, it makes it drone.

K&N oil filters have a 1" nut on the bottom. A 3/8" drive socket and 12" extension work well for removal.

Three (3) oil / oil filter changing tips:
1. My hydraulic line runs in a U-shape run right under the oil filter drain chute discharge on the front side of the frame rail. Made a mess the first time I changed oil. Now, when I change filters, I remove the one holding bracket (8 or 10 mm hexhead capscrew) and pull the hose of of the way. Cuts the mess way down.
2. Crack the filter and let it drain slowly, a little at a time, until most of the oil is out of the filter. Draining the filter contents more slowly prevents the gush of oil from overrunning the spill tray. This technique also reduces the mess and keeps your frame rails and garage floor clean.
3. Consider installing a Fumoto oil drain valve (think it's F106N) to speed up the crankcase draining process and eliminating mess. With a hose on the end, you can drain directly into empty 1-gallon milk jugs for disposal.

You should be able to tap the shift handle to the left and have the EVIC display go from "D" to "5" and you will be in 5th gear. Reverts back to D when you shut down the engine. This move disables MDS so HEMI stays in 8-cyl mode.

You can drain crankcase oil to a pan with -or- without the hose.

Will a tuner with the CMR tune or any of the factory tunes get rid of the tick? Also does it run alot better with MDS disabled?

Re: 08 hemi

Got 2 cents on this: I've been curious on this subject as well and have recently been trying. the "trick" where you tap the auto-stick to the left, taking it out of D. It's been working real well: seems to respond a little better and have better shifting points(maybe?). Also - i know the MDS "shudder" that someone referred to and I have NOT experienced it with MDS off. I too want to keep MDS off - me want my full V8!! Keep the info coming! Thanks!!
