Also thanks nyet your the best
So I was planing on going e54 next week and get that dialed in now that I'm getting close on 91. I'm currently running a 4" maf right now and was hoping to up the boost into the 32 psi range. I would rather not go to a bigger maf. What would you suggest? Get into a hpx and start over or can I underscale this 4"?
You dno't need another MAF - you aren't anywhere near maxing this one, and you don't need it to underscale.
You can also underscale in MLHFM in the top load cells and compensate in KFLF as described in the wiki... that way you can underscale just a touch at the top of the load range.
