Default retune with bigger headers?

I'm upgrading my long tubes from 1 3/4 Hookers to ARH 1 7/8. I don't expect any significant gains on motor but interested to know if my car will need a re-tune. Some have told me the car will run leaner but I haven't spoken to anyone with real world experience.

Any/all help is appreciated

depending on mods you may have actually lost power instead of making hp going to that big of header...

all depends on the rest of your setup and your expectations wether a tune is worth it........

I prob should have mentioned motor is a 395ci stroker (currently makes 470rwhp/485rwtq)
Will also be adding n20 down the road but for now don't wanna beat on the car if there's a chance I could hurt something
