Not only that Brad, but the stock programming is set to run extremely rich to begin with.
So having the MAF fool the PCM into thinking that 24lbers are 19lbers is not going to change the PCM's programming in any way. It's still going to run the car rich just like it always has been. Just not "even" richer by just plopping in the 24lbers by themselves.
It will Always need dyno tuning. 'nuff said.
