Max boost on new setup.

[91TSI505]

Please no flaming,Ok heres my delema right now,since i blew my 14b i have added:Evo exhaust mani,B16g,Walbro 255,s-afc2,Ext dump,3" Exhaust,NGK bpr7es,The 550cc injectors are next and i wanted to get everyones opinion on what boost level to run.I have heard people say 18,19,20psi.This will be on 91 octane gas/Stock SMIC,I have no logger though i will be getting one very soon,so right now i'm tuning as best i can with my 02's(I know its not the best method but i don't $hit money).I did do a search but did not find anything very close to this,Thanks in advance


In case you wanted to know my next mods are:
1.Logger/EGT
2.FMIC/HKS SSQV
3.Install my 2600

u should be able to run 18-20psi without any problems with those fuel mods after u install the 550s, but i would keep it lower untill u get the logger to properly tune when u can see ur knock and timing advance
and i would change ur gas station and find one that has at least 93 octane premium gas, never skimp on the octane to save a few cents a gallon, always get the best and highest octane gas they have, i only run sunoco 94 octane in my car(its ultra premium, they have 4 choices at the pump), higher octane means less knock which means less timing getting retarded by ur ecu, which in turn means u can safely run slightly more boost

Well SOME of us don't have the option of anything over 91 octane unless we spend $4 a gallon.

the sad thing is...bad gas=...kaboom...so if u wanna spend the money to upgrade your car dont skimp on gas because it goes a long way

so all those mods and 93 octane 20 psi is ok?
