Just recently replaced my headers & h pipe on my 14' GT. I had already had a tune with the car bone stock when I bought the Ngauge from Lund racing. So the question is, would I need a new tune/re-tune since the 1-7/8 & o/r h pipe have been installed? Any help is greatly appreciated & welcome. Thanks!
