LOL,.......SLP 85mm MAF and an SLP tune and mine just throw'n up the same code about 2 weeks ago!
I have a WS6 hood w/ deleted rain reflectors and I thought that there would be a time when all that air get'n shoved up inside would mess up the fuel to air ratio and send me a "lean" code. But I didn't expect it to be almost a year aftyer the mod. So now im think'n that I might just have some dirty *** fuel injectors.

All "too lean" means is that you've run out of trim
range and it's pissed. But, why are you suddenly
too lean, or are you in fact lean at all?
You need better tools to see -where- the +25
LTFT sits. If it's the idle cells and maybe Cell 0,
it may just be O2 sensors out to lunch and false
trimming causing all the complaint.
If you picked the wrong SLP MAF you might
have an added lean error, maybe too much
along with some pre-existing problem.
But there's no point in guessing about it, you
should add the mod list to your .sig for us who
are too lazy to go jumping around the 'net to
look.
