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

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!




*DISCLAIMER* please keep in mind i'm not bashing or defending any tuners...just making an observation.
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.
You sure about that rev limiter deal Jangy? Seems odd they would raise this and not a mph limiter.




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.
