Newbie timing question
Longtime reader and have done a few mods but I need your help!! I was trying to time the truck last night that bolt on the bottom is a pain in the *ss anyway about my truck
93 w/PW inj 12cm turbo housing pyro and boost gauge tweaked pump. I know you will all laugh but which way do you turn the darn pump to advance the timing and about how far?? I move it towards the engine about 1/2 inch and from what I have read it should improve boost and lower EGTs but my boost went down ?! on a hard pull I could get around 30 psi but now I on;y get around 22 any help out there??????
Thanks to all
Dan
