I'm at the point with my S3 now where I am ready for mapping...
I've got the AS CAI, milltek full system with sports cat and LOBA high pressure fuel pump.
My dilemma now, I have been recommended shark performance which offer the generic stage upgrades. I've also been recommended a custom tuner who does actual live mapping on the dyno or the road.
My thoughts on the generic stage upgrade maps a tainted due to my experience with my corsa VXR. I had a generic stage upgrade done by a very well known company and the fuelling wasn't right which ended up costing me more for a fuel pump and pressure reg.
My thought on the custom mapper, there are some good and bad tuners out there. I don't know enough about mapping to say who is good and who is bad.
The guy who has been recommended to me doesn't advertise a lot as his garage is very busy, he is a engine builder rather than an IT guy turned tuner who is trying now to push the tuning side of his business...
Google searches show good reviews of the chap but there isn't many of them. He is apparently well known the scoobie world.
I do like the idea of a custom map as it will be mapped specifically for my car.
What do you lot think I should do.
