I have a sticker on the underside of my hood that says there was a dealership approved modification to my vehicle and that the modification is CARB approved and gives the following info
part #mn132874 (believe is the ecu)
vendor E6T34880H2
rom id 941714
dealer 28078
engine TSB-04-13-007

Any input? Was this just a repair done to the ECU or was it an actually modification?

 

It sounds like they did a software update to the ECU.

 

make copies!!!!!!!!!!!! ;p lol
