ecu tune and 175mm crank pulley
I'm going to do an ecu tune on my otherwise stock 06 E55. All maintenance is up to date and the car is in great shape. It has stock cooling with the Bosch 010 IC pump.
A 175mm crank pulley has been recommended to me along with the tune. After reading a lot of posts on sc pulleys, crank pulleys etc.. I'm on the fence on doing the pulley and am looking for opinions from anyone who may have had this set up for awhile.
My concerns are reliability and drivability with the different crank. From what I understand the car would feel the same driving around town, but really wake up when you get into the boost.
I'll never take this car to the track.
Thanks for any opinions
