Dyno please.

This sounds very interesting. An estimate of the total hp gain we are looking at will be helpful.

Diesel Benz

0.4 hp or so at full acceleration, 0 at steady speed.

Edited: this is for the pulley, have not looked at their ECU update.

AMS Performance

Hello,

Gains in the midrange will be roughly 17-20HP/TQ at the crank for the combination. If you would like to do a Dyno comparison for us we do offer an additional $75 discount for our AMS Dyno Rewards program (special rules apply so please contact us first regarding this).

If you have any further questions feel free to contact us via email: sales@abedinmotorsports.com

Have a nice day,

how much does this package cost? Im guessing it will void the warranty?

The price is stated in the first post.

oops, thanks for pointing that out.

The ECU can be installed at a DIY easily?

AMS Performance

yes its not very difficult to take out and ship it and then reinstall. The crank pulley is also very easy install for any authorized MB Dealer or properly qualified MB shop (normally 1.5 hours is the standard labor rate depending on the car). Hope that helps.

AT THE CRANK !!!!!!! Now explain to the non techies here what they will see at the wheels..............

On his website there is a dyno graph from my dyno when i had it installed on my C55 I picked up about 15whp in the though out the low and mid range and 20wtq.

You may have read a post were my AMS pulley failed The dealer tied to blame the failure on bad install but there is no way you can install this part wrong. What really happened was the dealer was told to inspect the crank seal, they even say they did, Said it was not leaking and when i drove off from the dealer the crank pulley slipped and almost caused total engine failure. The dealer said they did not remove the pulley (thats BS) Funny thing was the car was fine when i dropped it off for a suspension leak. Thank god this pulley was made out of aluminum or it would have toasted my engine.

I feel its a good product and your shifts will be smoother for sure. The pulley is much lighter than stock and uses the same mercedes stock belt(s).

Not only did I like this pulley, AMS send me out a new pulley after mine failed due to dealer error. free of charge You cant beat that kind of customer service. Its just to bad that I dont think i can put the new pulley back on because my keyway on my stock pulley had to be modified to except the stock pulley. I really do miss having this pulley on my car.

I give this pulley a good product
