Recently purchased 04 av6 did the infamouse 4 to 3rd shift and pop there it went after 199k miles, so ripped the old motor out and have a j32a3 ready to roll, my question is how lean will it run with the j30 ecu? Funds are tight due to swap costs and wanting to install a new clutch while motor is out. Plan on going with OEM replacement unless there are any suggestions? And also WHO HAS A 04 Tl 6 speed ecu??!?!?!
