I Was Wondering If It's Possible To Put A 1999 Concours' Computer Into My Regular 1999 Deville So I Can Get The 112mph Barrier Knocked Down? Will There Be A Conflict Because Of The Different Engine Outputs? I Mean Will It Harm Performance Because The Computer Will Think Its Operating A Concours Engine With The Different Cams And Stuff And It Is Really Just Operating A Regular N*. Mainly I Just Want The 112mph Barrier Gone.

i posted about this in the deville section. you cant just swap the comp. you need to swap the trans the comp and the cams.

I just posted a similiar thread in the N* forum.
