Beau--Which 2 local are having issues? Emilio has car issues, he still does, even with the MPI out. Who is the other, that MSP I did? That could have been my fault because I learned not too long ago how an MSP needed to be tuned. He also had prior issues with the car, but who knows, it's gone now. You can't bring Eli into this because his ran great for the entire summer before he changed something.
Climate does have an affect, but I lived in MD where it got to the high 90's and sometimes in the 100's and then in the winter it got down in the teens and my car drove fine the whole time. I can see altitude changing things, but with xtra injectors you shouldn't use the purple TM wires so it is easier to tune. If Jeph's car didn't run the purple, the drive up there would have been different, much smoother. There are faults with ANY system out there, there is no perfect system. People need to make their own INFORMED decision. I always tell people that if they don't want to tune, go with something else.
We all need to be adults here and let it be. Some people like it some don't, that's how the real world works. I know there are shots back and forth, but it's got to end sometime. People can bash ANY product as much as they want, there is ALWAYS going to be someone else who will still want it.
edit: Oh yeah, I am in no way saying that Jeph's issue was the purple wires, I still don't know about that one.
