I took my truck out tonight with the scanner. I flogged it pretty hard once and my dam LTFT's went to 22!?!? Wtf gives with that crap? I only saw 1.5KR during that time. I hadnt ever seen this before. **** as of now, its still on modified stock tune running the 24.7 injectors. Any thoughts on what I should do or look at?

 

Did you check the engine bay to see if any vaccum line or ducting came loose? if you intake tube came loose between the maf and TB, I could see those LTFTs spiking up like that.

 

What where your mods to the stock tune?

 

DC,

I never really thought of doing this but.... I think my intake tube is coming apart. Im gonna go check that here in a few.

Turbo,

All I did was totally kill TM, up rev limits, top speed, and tweak the tranny around.

Also, the LTFT's bewteen banks at cruise only differed by like 1.8 or so.

 

Did some checking and my intake tube is ok. Im gonna try 2 new O2's this weekend.
