MRC 500 Audi S4 556bhp/546lbft : my daily driver ;)

556bhp/546lbft, the torque has dropped from last time, probably due to being half 95, half 99 fuel. Couldnt avoid it, Tesco ran out of 99 and I had to put in enough to get me to the next one.

MAF housing changed for a meshed one, air filter changed from stock to MRC/ITG and part siezed rear caliper fixed since last run at 530bhp/600lbft

@amletothelegend Oil cooler is now an external one mounted where the left hand intercooler was, pistons are standard and original, turbos are genuine borg warner RS6 k04's which were 5k old then refurbed before going in.
