Last year, I dragged the RS at the local 1/4 mile track and got a best of 12.7 at 108. This was with gutted cats and unitronic software, which was already flashed by the previous owner.
This year, all I did was send my ecu to Marc and what a difference! Ran two consecutive 12.1 at 113 and 112 respectively. The launches were incredible as well.
This car has stock intercoolers, and pump fuel.
What I love most about Marc's tune, it's very consistent. With the unitronic, the extra boost heat soaked the intercoolers and the car for slower and slower by each run.
