My friend has a B5 S4, with RS6 turbo's modified to fit. Larger injectors, high flow pump etc. Full details of all hardware to be confirmed, but will be built and ready for mapping in the next few weeks.

We are in Northampton, so obviously MRC aren't far away. However, they wan't best part of £800 for a live mapping session. Is there anyone on here that know what they are doing, and at a reasonable price?

Thanks, Tony.
