i just bought this greddy turbo kit from a local s2k owner. his is a ap2 and has the turbo installed for like a month and sold it to me. and i just finish installing it, i'm wondering do i have to re-tune the Greddy e-manage since it is tunned to his ap2 and i have an ap1.
my question is do i have to have my car tune or can just plug the e-manage in and use it fine?

 

I believe there is a wire that was changed on the plug and play harness in addition to the basemap. You will have to change the wire and get a new basemap or get it retuned.
