Richmond VA Dyno Day Results 5/4/13
Well this is good news. It makes the car run richer. WAY RICHER. Once you lean out that spot it will produce more power. What did we learn from this? Needs a tune. (I have a tune and my AFR there is perfect and I have a nice pick up in the dip. Putting on my RevWorks headers Friday and getting retune on Tuesday to hopefully see no more of the dip.

(You could even say the resonator leans out the AFR's)

The only real way you will get conclusive data is

Baseline.
Dyno with resonator
Dyno without resonator
Dyno with resonator tuned
Dyno without resonator tuned

Since removing the resonator makes the car run richer. (also before my tune my car was running extremely rich)
