The New Seafoam??
My 427ci LOVED when I cleaned it out after 118,000 miles. Totally changed the way it accelerates and idles.
Just know if you use Sea Foam you will only be cleaning 3-4 cylinders at the most....and almost NONE of the intake and really none of the valves and runners in the heads.
Mopar...........................

Now how the **** do you compare the two? I've taken 90k intakes off that looked like the one posted earlier. You need to pull the **** apart, look, put it back together, treat it, and pull it back apart. ******* idiots, oh the seafoam smokes more so it's better. wat the ****.
Pour liquid into the intake huh, big bashing on me for saying that was a bad idea. Now a year later what are we all going to do agree that it is a bad idea and I was right? oh no.
walmart stocks seafoam now, put that on the wifes grocery list.
Gotta have FOAM.

Sure, the Mopar stuff would clean alot of that **** out of there bigtime. But there's something wrong.
When you cruise at a steady 50 mph, then nail the pedal to the floor, do you leave a trail of smoke for just a couple seconds, then it clears up as you continue to accelerate?
Or maybe do you leave a constant trail while accelerating the whole time?

The Best V8 Stories One Small Block at Time
I was told by a very reputable builder, perhaps the best, that its very bad to just pull out and start driving immediately after start-up, especially with a forged set of pistons. Because they actually are not yet tight in the cylinder and actually move around. Obviously they move a tiny tiny amount, but enough that you'll wear them prematurely if you don't let them warm up for a couple minutes. One of the reasons the C6 Z06 427ci has cast pistons...so it can pass cold start emmissions easier.

With the MotorVac treatment, I measured a 2.5-3 mpg gain highway/city and have much faster engine starts.

I had the service done at a garage, which had the machine, and it cost me around $100. Its more expensive than a do-it-yourself treatment, but I was in-and-out in less than an hour, was hands-off, and didn't have any lingering effects after leaving the garage. (All the cleaners were worked out of the system.)
Did they let the foam sit for 45 minutes to soak into the grime and break it up? Or do they just run it through the idling engine?
Also, how does it clean the fuel lines from the gas tank to the rails? Do they remove the fuel injectors to clean them? I'm wondering how they run fuel cleaner through the fuel injectors without filling up the cylinders with fluid after the cleaner runs through them to clean them?
I like to keep my entire fuel system clean with an entire can of Sea Foam into 1/4 - 1/2 tank of gas every 3-4 months. It cleans everything from the fuel pump to the injectors and all lines inbetween.

If I recall correctly, they put the cleaners in to the machine and then hook it up to the fuel rails. It then sucks gas from your gas tank in to the machine, (you can see the tank opening on the front) which it uses to dilute/mix the chemicals. That mix is then circulated around the rails and then used for the burn phase (with the engine on) where its sent through the injectors and to the cylinders. (Its supposed to clean the injectors in place through that last phase.) It does not clean anything from the tank to the rails.
Here's the company's instruction video, which shows additional details and the full proceedure (get out the popcorn! - its 26 min. long): http://video.google.com/videoplay?do...motorvac&hl=en
