I have three main positive points following the installation of the P-Tronic tuning box on my Grand Cherokee 3.0 CRD 250 bhp. 1/ The starting is more incisive with an immediate response to acceleration 2/ I have more engine flexibility at low revs (under 1500 rpm) 3/ I notice a significant gain in consumption: the box allows me to go from 11.3l to 9.6l/100 km.
