dear members. my vitz 2000 has a slow pickup in cng and the mechanic told to replace the PVR advancer with NeoTech. while PVR advancer is working. Plz guide iz that right to do. or just he is bluffing...
try tomasetto achille adv i m using it since two years,no problem yet but try different mechanics if your problem can be solved without changing advancer
if ur car is knocking on cng and/or is idling rough then u first need to rectify that as it will give hard time to ur advancer calculating the rpm at which it kicks in...
First tell if your car has manual transmission or automatic.
also get ur car tuned by enercon.
