I know about the .2 sec loss on a Mass Air conversion, saw closer to .25 on a Mustang I converted years ago... I ran the same MA setup on a Trick Flow headed & cammed 5.0 in a '88 T-Bird, had decent drivability and went best of 13.11@105 on the motor... With more converter it could have dipped into the high 12s fairly easily... Should be back on the road this spring with a 331 and a lot more converter(3500 vs 2600)....
The MAF setup goes full base-table at WOT anyway. The big issue is the square-root sign shaped timing table, which Jay Allen always remarked was easy to get around by locking in your timing with the SPOUT out.
My car went faster when converted to MAF. But I used a Pro-M MAF, not a stocker, which at 55mm, are insanely restrictive.
My car was 14.2 @ 99.8Mph stock (speed density), 13.8 @ 101 MAF with underdrives and an E-fan. Cut a 107Mph trap, bottom 13's (should have been 12's and a higher trap, but broke the transmission) on the limiter in 3rd for its only pass with the new H/C/I setup (ported GT-40's, TFS-R, TFS1 cam...etc), made 270RWHP on the dyno, pig rich.
