[T3] Question about D jet idle issues 73 T3

Tue Jan 26 21:16:10 PST 2016

 I know when the heads were done I recall a step and all they did was fly 
cut the step a bit so the cylinders would seat proper. They said it would 
not affect the CR much yet the new cylinders and pistons were flat top the 
original had a dished center.  I know they used to post the ethonal content 
on the pumps , now I don't see it. I think it's still E10.

 How would I go about adjusting the FI to get it more rich ?
