See mods below, subtract:

MAC CAI, Underdrives and Timing Adjuster.

Add:

Vortech > 7-8 lbs. boost, Denso Iridiums, 255 lph fuel pump, 38 lb. injectors, professional dyno-tune.

I'm shooting for 400 RWHP, but it's my daily driver so I don't want the tune to be too agressive. Now, do I stay with the stock MAF or go bigger?

400 is borderline on the stock MAF. If you don't plan on going much higher than that I'd say go with the 9mm LMAF.

edit: yeah, 90mm (i hate laptop keyboards)

If your tuner cant tune it with the stock MAF, I would go with a 90mm Lmaf. That is what Im running.

Sounds like your tuner didnt know what he or she was doing.

Are you using it as a blow thru? If not, I don't see how you were pegging so low. Maybe a bad MAF.
SCT MAF is no better than the LMAF unless you are planning to exceed the limits of the LMAF, then it becomes the better option.

Also to helty, neither the SCT or LMAF are caibrated to any injector size. They are calibrated to a flow/voltage curve which is put into the EEC. The EEC holds the injector values.

LMAF

You must be retuned to change MAF.

if they cant tune a maf at a whole 315rwhp, they cant tune for **** or cant troubleshoot broken/damage parts.

Unless they are using it as a blow through wich will cause it to peg much sooner.
