I installed a new 5 inch exhaust the other day because the old system was getting pretty rusty. Anyway, when I got home tonight I went back to admire my nice new stainless steel exhaust tip. When I looked at it I noticed a film over it so I went inside and got a paper towel and some windex. When I looked closer I noticed it was white soot and not black. So my question is, could I have a bad injector, or is it something else? I also noticed tonight on my way home that from 1500rpm to about 2300rpm it pulls very nice but after 2300 or 2400rpm it feels like stock again. I know that it starts to de-fuel at 2700rpm. It almost feels like it is starting to de-fuel at 2300rpm if that makes any sense. It is also much more noticable in 4th and 5th gears. TIA for the help.

How did your pyro look? Id be inclined to say its just some of the galvanizing or coating from your new exhaust burning off.

No matter how hard I try, I cant get the pyro to go over 1000* empty. When I am loaded, it can get up to 1100*. I never would have even thought about the coatings on the new exhaust. Thats why I love this place!! I cleaned it off and I will report back in a couple days. What about the de-fueling problem? Could it be in the VA box, or is it something else? Anyone have this before or am I the first? Thanks again
