BMS Intake
CP

Along with the Pure S2 kit I am installing:
Pure Inlet
N20
TMAP
VRSF Cattless DP
N20 TMAP
BMS Meth Kit

I have a few questions before I have the parts installed, hoping a few of you can set me in the right direction.
  • How much power should I be able to hold on my stock DCT with the MHD BEF?
  • What BEF should I be using with CPI (Meth) on 93 octane and stock fuel pump otherwise
  • Can I run a 20 meth additive on map 3 for an 18lb target? (with the N20 TMAP)
  • Should I run dual CM5 with these settings or single CM5?
  • What Water/Meth content should I go for?
  • Do I need to replace the oil feed lines (with new OEM ones) to the turbo as part of the install? Is it recommended?
  • At what point (psi) will I most likely need upgrade my fuel pump?

Thanks for any recommendations you can give!
It seems like alot of people start with the factory HPFP, run into issues, do a bunch of stuff to try and work around those issues, but end up going with an upgraded HPFP.

I posted a thread a ways down in this forum about b58's HPFP being a usable upgrade for us n55 guys. You can pick them up for 200$ish bucks on car-part.com and they flow 17% better than ours, which should be enough for big power. You have to make slight modification for it to fit, I think I have the link in my thread.
