big afr change?
how big of a difference in AFR's would decatting a downpipe and changing the length of the chargepiping cause? my AFR's were right before i did that and when i changed everythin the AFR's shot thru the roof and i just changed my fuel pump to a walbro and now my AFR's are like 1 point lower. is it still a fueling issue or did i manage to find more air?

would the volume of air be changed enough to make me go from 11.7 too somewhere in the 14s at the same psi? i been talking to vince and he thinks something is clogging the fuel system but i just changed the fuel pump and it didnt help and i dont got a long ass gauge that can reach in my car

I didn't realize you changed the CP when we were talking, I thought you just said you de-catted. That will def need some readjustment and explains why it goes lean and still pulls hard. Like I just sent: Any car Ive had a weak pump in would drive normal, go lean and the power would flatten out when it did. Plus you can see the IDC% sky rocket when that happens and the car never goes richer.
