replacing airbridge
Would going from a stock airbridge to a powerduct air bridge require a retune? I know powerduct claims the flow is different but is it enough different to affect the tune? I am just planning on switching it for cosmetics.

Hey Randy, did you run this question by Doc by any chance? I've seen various (sometimes conflicting) tales about this over the years. Based on their particular experiences, some say yes and others say no. It may also be more of a year-dependent thing with some having different MAFs and IAT sensor locations, etc.

Going from a stock coupler to a smooth coupler will actually slow down the velocity of the air movement into the engine. The PCM has firmware the interprets the air movement and changes several tables the PCM uses for its fuel management program.
Most will not notice any difference unless you are going to drag race and depending on a number of variable it might very slightly increase or decrease your times. Many will notice the difference with a rougher decel because the car is running leaner. A tuner can take care of both situations, but unless you autocross, HPDE or drag race it may not be worth it. However it will increase the noise of acceleration and most will "feel" improvements in the butt-o-meter.

When you say "it will increase," you mean noise and butt-o-meter will increase with the new tune or without, or both?

Wasteful is to retune a stock engine. If an auto you might want to do some trans tuning or adjust the fan turn on temps but otherwise just leave it alone.

The best way to go a larger air bridge and CAI, integrated into one unit, is to buy a Callaway Honker. Smooth looking and flowing, OEM quality and works great. All in one piece.
