What should MAF flow (g/s) @ 3000 rpm on an 86 305? My MAF seems to top out at around 14.I've got no acceleration past half throttle and/or 2500 rpm. I'm thinking bad MAF.

 

Here is an interesting read:

Among other things it mentions the possibility of low fuel pressure contributing to poor performance at higher throttle positions or whatever. It looks to me like it is rather difficult to correctly troubleshoot the MAF sensor.
