My 325i pulls hard all the way to 135..... you can almost trick it into 138-140 range because of the way it limits the top end (thru shutting down cylinders slowly)... The Chip company I am talking to is promising top end to increase to 155-160 like beemerworld said. 5th in auto should not matter, mine pulled great in 5th.. remember your rpms are up, so torque is up.... it's a good thing.
