Good day
My Patrol received a chip and stainless steel freeflow exhaust, the head was gasflowed and they did some modification to the airfilter and the cam timing and then it was dynatuned. The BEFORE run was 82.5kw and 234Nm on the wheels and AFTER was 99.8kw and 261Nm. In November last year I did a dynarun at another company and the results were 92kw and 270Nm. Although the results from the 2 companies differ there is definitely an improvement in power. The acceleration from 0-100km/h is faster. At 120 with the overdrive off I don't have to step so hard on the pedal to maintain the speed on an uphill.
