I recently rebuilt my 3vze, oversize valves, oversize cams, performance piston heads, and ended up using thos "upgrade" fuel injectors guy is selling on ebay which i have no complaints about. Headers to a flowmaster no cat.
Runs fine but my question is tuning. Currently sitting at 12* advance. But it needs something. Was thinking of opening up the afm leaning her
out a few clicks. And advancing the timing a bit more but honestly tuning, especially built motors is where my knowledge starts to lack...
Any education or suggestions on which way to go here would be appreciated.

Edit: i shouldnt say she runs fine, she just runs and drives. Its lacking somewhere. I know it needs some tuning

 

Get an air fuel gauge one that is accurate. That will tell you were any fueling issues are.
Not saying yours is the same but my cam swap has been soso perf. I recently figured out im maxing the afm after 3500 and going lean. Ymmv.

How do you like the oversize injectors? Im gonna try to make an adjustable fpr for mine when i get some time but was also thinking of them.
Side note my 3.0 is just crower cams and a full stock rebuild.

 

The injectors are supposed to be the same flow rate but unlike the stock squirters they are supposed to atomize the fuel. Havent noticed much difference But a little better mpg's.
You maxing out the afm is making me nervous. I figured the little guy could handle a cam. Now i really want to check mine.
