Progressivly getting leaner??? Ok I had my car tuned last July, and it would sit around 12.6-12.9 at WOT, since then I have added a ported TB, FTRA, and the fast toys ported MAF ends. The car was tuned on a de-screened maf btw. But I noticed last week that WOT a/f was about 13.3-13.5 and this week its about 14.3-14.5 
. I changed both o2's, the drivers side one and the wideband one on the passenger side (since the wideband o2 was shot anyway) and I changed the fuel filter. After all of that I noticed no change in my a/f, its still mid 14's. Ive never heard of anything similar to this happening to anyone else. Anybody have any ideas????
Thanks in advance!
