I have a 2000 A6 2.7 6MT that I want to use exclusively for track use. Thing is that I want to extend the car for longevity. I have two 4B0907551K ecu's one was already flashed with the S4 rom and the other is completely stock.

Is there anyone out there can help with making a custom Rom that bypasses the usual cat's and EGR's ect and includes only a modest bump in boost and timing for my race car to use ion 6hour long races?

Car is running Stock Turbo's but it has 3" Downpipes and a full 3" exhaust sans Cats.
I am planning to remove as much CARB compliant stuff I can from it tomorrow when we start stripping the interior.

Any and all help would trill be appreciated.

\Thank you and happy holidays to everyone
