hmmm, who's car was that??? Didn't u guys say the 80mm was easier for tuning than the 90 as well???

And I guess one has to take into consideration the size post-MAF. . .it might be good for increased air velocity to have a larger MAF that funnels down into the narrower UIM opening (or in this case, gets routed through the intercooler). . . .
