A tune is a must after a header install if you want to get maximum benefit from them.
and why wouldn't you want the most from them??

My tuner runs a wide band O2 on the street while driving, and when tuning he compensates for the Vararam as it tends to lean out the car with speed. I think you definitely need to tune the car after these mods.

I waited to tune my ride until the cam change, no problems without the tune. I used the Vinci Programmer after the cam, and thinking back I should of got the tuner before my mods. That way I could of had my tune from the beginning.
