Had a remap done a few years ago on a 3 litre diesel by DMS Automotive. Told would raise bhp from 237 to 295 and torque from 500 to 600. Had mechanic do it on my driveway. Big hike in performance. Mid range really impressive. Had quad sports exhaust fitted as well supplied by spires jaguar.
Had some think I drive a 4.2 SVR.
