Why do people think these are low numbers? That's 25 HP gain over a straight 3L swap... Anyway, the MAF is not a tuning device when you're running a totally custom engine set up. Take the MAF flow sheet to the dyno with you and get a custom burn if you want the combinations true power. The MAF alone will not make it run perfect... ever...
