does anyone use a computer laptop program to modify their engine stuff? Im looking to change my rev limit someday... not wanting the dealership fooling with it but to do it myself

 

no one has been able to modify the ECU in the TL for any purpose. I doubt you will be able to.

 

You will need to run a standalone ecu if thats something you really want to do. Like mikepa said, no one has been able to modify it. Honestly, what would be the gain for doing that? Do you have a bunch of mods or something?

 

chyeah duh....twin turbo with enough +5HP stickers to peal back your eyelids

vroom.............
