Hpx-e close to being pegged

I took a log at 18lbs of boost and my mafv is at 4.5v at 5300rpm, my hpx-e is in a 85mm housing, should I just put it in a 4inch tube? Will I have problems with it being in such a big housing? What options do I have? Or should I not worry about it until I make a full pull to 6000rpm.

it usually takes 50% more power to go from 4.5 to 5v youll be fine

My maf pegs at 4.7 volts, the last time I pegged my maf it was at 4.7 volts. I am guessing because of the resistance in the wires.

If I decide to upgrade to a 4 inch housing, will run into any problems dialing it back in as far as resolution?

Also one more thing, I found a deal on some FIC 1200cc injectors and will be stepping up to those from 80lbers. Will it be difficult to get them to idle out? I will be on e85. Thanks for your responses.
