new downpipe need a retune
i'm changing my 2.5" downpipe to a new 3" one. The car is running in a safe 11.2 afr's at WOT. Do i need a retune or i can test the car and see how she feel? i'm just changing the old cause a big dent on it.

Larger downpipe will increase spool not decrease. You wont need a complete retune but the tune will need some cleanin up. More flow = more fuel
