Ok guys...what is the deal with this chip..they claim 511 hp with Gold 93 octane. All good sources I have say this is impossible without a pulley/ECU (the supercharger is pulley-driven) combo upgrade. Has anyone tried this???

 

If they are claiming it at the crank, then it is possible. Keep in mind you are saying 93 octane, so the car will need a tune to really use it. Find out what the details are. How will they prove it, etc? You prefer to do an ECU upgrade WITHOUT Pulley? The Pulley is the best bang for the buck, bar-none.

A large pulley and chip could easily give you 50+ HP and TQ

 

i've been wondering why nobody brought up powerchip's claim of 42hp from a 55 tune with all the other tuner bashing going on around here.

 

I think the 511hp claim comes from the fact that the normal car is 496hp.. The 469hp claim that MB puts out is underrated and we all know that.. the cars dyno 411 - 420 at the wheels which puts us at 500hp crank.

Powerchip is basically saying you'll get 11 - 20hp from a tune which is true.

All of their numbers are put into the advertising from real dynos they do..

 

Not sure but members on this board and others with 63 had their warranty void with a Powerchip ECU upgrade, something to consider if your still in warranty.

 

Anyone with a 63 that has their ECU programmed needs to make sure that the rubber SEAL is put back onto the ECU between the top & bottom half.. if it is not resealed MB will know its tampered with..

This is true with anyone who tries to flash your ECU.

63 ECUs cannot be OBDII flashed.. they have to be done on the bench and the cover has to come off the ECU.

This was discovered recently (from what I know) and now Powerchip is putting new seals back once they put the ECU back in the car.

 

wait, you have to tune your car to use 93 octane?? dont we all use 93 octane in our e55s?

 

Cali and some other parts of the world only have 91octane available at the gas stations...

In Canada we have 94 octane at the pumps.

 

ohhhhhh ic.. well ive been using 93 octane since i bought the car.. like every other car on the road like this.. am i not suppose to? its only 87, 89, 93 here

 

Don't bother with Powerchip, I've seen too many mixed results. Go with RennTech or EvoTech, as they provide a much better tune

 

Victor, are they putting back the exact same seal? Would it still be possible for MB to find out if a new seal is placed? Also, I heard some parts of the ECU has to be soldered back into place

 

yep that's my understanding also but i just wondered why so many people point fingers at veloce when powerchip has been making the same claims for years.

 

the other poblem with Power c. is they do not delimit the top speed.

 

Ok, some false stuff flying here.

First, Victor is correct in saying that these cars are underrated. Most have 490+ HP instead of the 469 that MB states. However, some have been de-tuned with an ECU update from MB. The PowerChip ECU tune does bring it up to 510+ at the crank. My car dynoed in third gear (stupid dyno tech!) at 436 RWHP....which makes it about 515 at the crank. I also have K&N filters.

Second, they DO remove the speed limiter.

Aaron with StealthAuto did mine and he was FIRST class to deal with. I got the 93 tune with the limiter removed. When I get a pulley upgrade, I will send it back to be tuned for the upgraded pulley for an additional $100.00.

Hope that helps!

 

Before I sold mine, I hit 178mph with a PC tune.

 

sorry, when i called them like 3 yrs ago they said no so sorry for the old info.

they must have changed it.

 

Has Powerchip been in here posting claims in every single section of this web site?

 

lol, no but their claims (which are very similar to those that veloce has made) are in countless threads in the form of a signature ad.

*DISCLAIMER* please keep in mind i'm not bashing or defending any tuners...just making an observation.

 

Yes, powerchip's numbers are too aggressive and not very realistic. Also, I know personally of at least 3 incidents on 3 different AMGs where the tune absolutely showed no gains on the dyno

 

Both claim BS numbers!

 

The speed limiter is not removed from ANY of the tuners. It is a rev limiter and it is simply increased. Powerchip's tune opens the E55 top end to over 200mph.

It seems to me that the issue with the 63s is universal and has nothing to do with the tuner. Does RennTech not also have to break the seal? I just think the powerchipped cars were the first to get flagged.

 

So they raise the rev limiter in top gear only? Can an e55 or e63 even hit the rev limiter in top gear?

You sure about that rev limiter deal Jangy? Seems odd they would raise this and not a mph limiter.

 

I think Kleemann move their speed limit up to 186mph. I was hitting the speed limit at 156 mph and i called Kleemann and they raised mine to 186 mph

 

I am not sure about the 55's but on my M6 the rev limiter is raised to 8450 or 8500 and the vmax is dropped. So the rev limiter is raised and the speed limiter is erased.

If memory serves me, my final E55 tune with PC definitely took out the speed limiter but I am not sure about the RPM's.
