Someone with VCDS will be able to check if you have a boost leak, the S3 is prone to them, the smoke tester will then pin point where the leak is.
The coil packs are also prone to fail after a remap if they are not new, I always ask customers to get new coil packs fitted on an S3 before a remap if they are original.
