Hi Peter,no I have not established if it is the right distributor,the people I paid to install it (ultra tune) should have checked but now have doubts,when I returned the van saying it was pinging under load he said they had almost run out of adjustment.When I got it back I had a look and the body of the distributor was centred,however when I retimed it I had to reset it almost all the way to the left,then I understood why he had said he had almost run out of adjustment,Why did I move it from where they had set it,because when I got it back it lacked any response and my timing light showed the distributor was well out of wack as soon as it was reset to 8 BTDC boy I got really good response but pinging under load.My thinking is get an analog engine analyzer to establish where everything is.I have three months warranty with ultratune but given the service with this mob I will take it to another ultras tune.cheers kiwishane
