All:
I posted this question, but realized I sorta had it buried in a thread about engine fault codes. So I'm bringing it front-n-center.

Among y'all who've gone to a larger TB and used the 987 airbox, are any of you using the 987 MAF Holder / Tube with success?

I'm getting codes P1126 and P1133 which suggest lean condition on both banks. (IIUC)

I know that many people are using the 986 MAF holder, but that didn't really make sense to me, to neck back down that way. It seemed to negate all the work to get the bigger diameter in there int he first place. y'know?

Waddy'all know?
