I went to the dyno last night but didnt have my timing cover on. I removed it completly. The guy dynoing my car said he couldnt tune cam gears or timing w/out knowing what base timing was so i was kinda stuck but he did tune A/f ration for now and will retune it for me in a couple weeks. Is there any other way to time the car not using the lower part of the cover. What are most of you guys using that dont have timing covers to check timing?

 

i usually just take the top part off...
