I've beem playing with the pump timing on my 86 6.9l. I here 9 or 9.5 btdc is a good number to start with? How do you go about getting there is the timing mark on the balancer at tdc or is it 7.5 or so? I'm using a Blue Point pulse adapter and the timing seems a little erratic is this poor reading on fuel line or worn injector? Also EGT's seem a little high I'm running a turbo 7psi max 4" strait pipe screw in about 1/2 flat. Will a lean condition cause high temps?

 

i never used a pulse adapter, i have the proper meter. i set all of them to 9.5

 

it just depends i advanced mine from stock timing 1/16 but i also marked the stock timing so i could go back if i needed to
