maf with FI??? i know its been discussed many times before but i just want a final answer so i can make up my mind as to what i want to do... is it pointless to use a maf when going with lets say 15+PSI of boost? am i better off with speed density? would a diffent maf make a difference like maybe an LPE 100mm maf?

Id like to know as well, this is something I haven't even thought of yet. I got a d-1 with the knowledge I'd boost the hell outta it eventually, and eventually is almost here.

would a bigger maf not max out as easily or is the size just for restriction purposes like to be less restrictive on the intake side?
and i too would like to know what lingenfelter uses on his tt 427 vettes as im having a 427 built for boost and soon will start on my tt system.

The maf maxes around 640 engine HP or around 550 rwhp...which is close to a stage 2 LPE car so all is good.
The LPE 100mm maf only helps some hertz issues on LS2's and an inlet restriction on high hp cars that insist on using a maxed maf. I ran a stock screened factory maf to 700rwhp, but it was maxed at 3400rpm....had to use rpm vs PE tuning above 3400rpm...not the best way to tune , but it worked....I'm playing with SD now and agree with INTMD8.
