I swapped to revo from a sedox map for my cr170. I had a nagging doubt after going to sedox, and Marshalls problems only multiplied that doubt. I wouldn't say my car is any quicker with the revo map, but I do have peace of mind now and that's worth a lot to me.
Really need to get a Revo and my Sedox side by side in VCDS to see if it's worth it to even switch over.
I have the same niggling doubt about whether mine is being kind to my engine I think I'm just hearing noises now where there aren't any.
So if anything, go with Revo for peace of mind
