Does anyone understand the way REVO actually works?
I'm seriously looking at getting my 1.8T REVO'd but I'm a little sceptical about it and basically don't want to screw up my car. I've heard people talk about it and say they can definitely notice a difference. My A3 is an earlier 99 so they quote it will get to around 190BHP from 150BHP.
Does the REVO software completely wipe the existing Audi MAP and replace with a REVO designed one? Is my original Audi map still safe ?
