How do you all do it w/ heavily modded motors? Do you just keep the A/F mixture between the optimum levels so that it burns the best? Emissions tests in NoVA are pretty damn nasty & strict (but probably not as stringent as you Cali headz).

 

I am trying to figure this out too.

 

call Nu Image in Springfield Virginia...they are shady as **** but they got the hook up on emissions...just dont buy anything from them
