American Racing Headers GT 350

Why did you not get a tune revision for the headers? Do you need one? Where is AFR before and after headers?

 

[Elnrownr]

There was a revision after headers

 

[cluscher]

Thanks for that clarification. Where is AFR on the current tune?

 

[Elnrownr]

It looks like a point or two about 12.0

Like 12.2-12.3
