Hello I was wondering with 1.6s rr and stock cam would I need a tune again, I did with headers.

How can you tell that you needed a tune with the headers? Both headers and 1.6 rocker will inhance the engine breathing and a good dyno tune will give you more a little bit more power with such mods, but I don't think you'll need a tune in the sence that your car will run fine without it.

 

I dyno tuned it. I was getting a10.8 af ratio when I installed the headers, and since im adding rr I woild think I need a tune again...

 

It is your money, if you want to dyno tune it again you may get a little out of it, but since you had it pretty much optimized prior to adding the rockers I don't think you will add much more then not getting it tuned.

If you didn't already have it tuned then it might be worth something. I say go with out re-tuning it.
