hi everyone I'm new to the forum.
I brought a 09 s3 with some mods done by previous owner.
He show me the receipts of revo stage 2 . But I find out it only has the miltek catback.
Will it be just stage 1 instead although it said stage 2 on receipts as some say you can't
Run stage 2 map without downpipe and high flow cat or de cat?!!
But just wonder should I put a miltek downpipe ??if I put downpipe and high flow cat do it need to map
Again if already on stage map?!
P.s bilstein b8 + kw spring. Haldex comp controller on the way...ka ka ka
