Not at all man its all good. When I drive cars or use equipment I get a good feel of how it runs and then develop muscle memory to it. What im saying is on this car to keep it at steady speeds, before this mod, whether it be 35, 55 or 80 I would have to apply about 15% throttle, maybe more maybe less. Now its more like 5%, so the margin of error has shrunk down drastically. Which is why the car is feeling very jerky and somewhat unpleasant during that short time frame when I'm NOT trying to tear up the roads, mostly when wife and kids are with me.

Don't get me wrong It's badass, but what Im disliking is the ability to control the speedo when im driving tame. The whole up down up down up down in mph is annoying, thats all, feels like my wife or ex gf's are driving. I just did the whole pedal reset thing just now. Did wonders for shifts but nothing for pedal/throttle.

Damn at that price its a no brainer. Drove the car another 150 miles yesterday. No problems with any of the pumps, alt or ac. As far as the sensitive feel of the pedal/throttle I'm starting to get used to it and enjoying it more and more. Seriously at this price, if you were on the fence, just place the order.

Here’s a quick write-up on why most people stay away from these. http://www.atiracing.com/products/da...mper_dinan.htm
Theres a ton of information out there.
Even assuming that the UPD unit is properly dampened to the specific harmonics of the M156, I know that I wouldn’t want my water or power steering pumps to turn more slowly than designed. Ok, your lights work, that’s super. But what is this thing doing to the rest of your engine. No thanks. Easier and safer ways to get 5whp. Cranks and other internal engine bits are expensive.
Nothing against UPD here at all, Shardul is a good dude. I’d just rather stay away from stuff like this.

, sorry guys I had to do it. Like I said on earlier post I'll chime in every once in a while for a longevity report. If I start noticing some negative effects or if something bad happens believe me I'll let you guys know.

. I literally just got home from driving this car. This pulley mod is awsome. I guess I was just being a little biach as far as the pedal sensitivity, as I'm used to it now. But it did throw me off at first. As far as AC, Alt, and the other belt driven pumps, everything is great. No problems.

Just checking in. Put another 1200 miles on car. Pulley has been great so far. Voltage stays at 14v. We've had strange weather in central Cali. Freezing in mornings then got up to 85 degrees for a couple of weeks then it started to rain for days. Heater and AC worked great and had no issues. Headers should be here this week so looking forward to "completing" all planned mods for this car. Well, maybe flex fuel too if we get the group buy price again.

I like the plug and play aspect. Quality seems better too. But It cost double what the other ones cost though. Id be down for the $1600 with 550cc injectors. But now I guess price is going up? First things first, ARH header install.

They certainly can't claim it's the same or no one would fork out the extra $1200. However, the power is in the fuel, not the kit. If it works it works, one kit will NOT make more power than another. If anybody tells you differently, be wary. There is no magic to it, the control unit alters the injector signal (based on input from a generic ethanol sensor that is the same in every kit I've ever seen) to compensate for the extra flow demands of e85. That shouldn't cost $1600. It's called AMG tax. The same afd kit for the M3 is $400 cheaper. For the Mustang it's $800 cheaper. All the same kit, only difference is the injector plugs. It's all a racket man

Not sure how that claim can be made without actually seeing the two kits side by side. The cheap one is plug and play as well fyi..

Sorry OP your thread is way off topic now. But, see Doc's excellent thread on his kit install from eflexfuel. https://mbworld.org/forums/c63-amg-w...installed.html
Probably time that Doc or someone experienced start a separate comparo thread. I emailed and asked AFD what I was getting for all that extra coin after being convinced to buy the kit Doc got, which is like $360!!. They told me that they weren't familiar with Doc's kit, but that they noted based on his thread it was making less power and wasn't "as plug n play" because of needing to seat the connectors or whatever, and that the kit appears to be "generic" in that it wasn't "designed specifically for M156" and uses inferior fuel line components. Just reporting what AFD stated to me when I inquired. I do not vouch or otherwise support any of that.

No need to apologize fellas, I'm all for this shyt. Good talking points here so why would anyone complain. I think the 1 thing that makes ec ff kit more enticing is the fact they will only tune their kit. That alone is worth an extra 12-20whp. But is it worth an extra $600-$800. Thats the real question.

That's my plan. Hate to throw away the $$ I spent on the EC tune but there doesn't seem to be a choice.

EDIT...I dont want to rely on e85 only. Its my understanding that if you tune for e85 then you essentially have to be running e85 all the time. I liked the idea of being able to run a heavy mix of e85 when I want to use the extra power it provides but not be married to it. Thats how eurocharged explained it a while ago.

Ugh didn't realize the 30 ponies was due to restrictive E85 tune. So their graph shows a jump of 18 hp from base run on gas to just E85. The full 30 is with tune. Wow, that's tricky. I don't see any asterisks next to the bold fonts claiming 30!
For example:
and
The C63 AMG put out an additional 30 horsepower and 31 foot-pounds of torque running on 70% ethanol.
THe more ya know. Group Buy CANCELLED LOL

Still, 18 hp isn't bad with no additional tuning. If I remember that was at 70 or 75% ethanol, right? For comparison, my 14 rw came at 60% ethanol (I can't run any more without upgraded injectors) so the numbers are pretty similar.

Back to pulley talk. AMG tech said install of this pulley is a lot easier than any other aftermarket pulley he's ever done. UPD provides install instructions and tech followed them to the letter and install went smooth. I'll post a pic of letter in a bit, if I can find it. Anyone planning on doing this install will need special tool to lock the flywheel. Its around a 2 hr job.
