Safety first..., What boost to set it at? Options

[DSM5]

MY car is stock when it comes to fuel mods. So what would be a safe setting for my new MBC? I was thinking around 14psi.

You need a FPR with a Walbro 255 or larger, and you only need the S-AFC if you change injectors.

you'll need a safc once you start modding it though period, especially when upping the boost. unless I am totally off on this...which is likely.

And what am I talking about anyways?!? Tuning is for pussies.

you never EVER need a safc, get a maf translator instead

yeah i am tuning just fine with my SAFC. i actually prefer the SAFC at this stage of my car because it is easier to tune with. you can datalog and tune on the fly and in the winter weather you can change your maps quickly and easily. when i am putting 300+HP i will probably upgrade to a MAFT but you can find SAFC's for cheap from anywhere, they are easy to install, and are very user friendly.

if you want to vent your BOV to atmosphere or are turning out very high HP number you might want to go with a GM 3"-3.5" MAF to clear restritions but an SAFC and a hacked MAF is a good place to start with when your uping boost on a stock turbo IMO.

try relocating your MBC to off of your intake manifold (if it isn't already there) it should hold more boost to redline. what are your duty cycles at high rpms? if you aren't knocking you should be able to up to boost a bit more. really the only real way to know if you are rich is to use a wideband O2 or maybe an EGT. i would just pick up an AFC and tune for knock at whatever boost you can hit without fuel cut (probably around 13-14psi in this weather i would guess on stock injectors with stock fuel pump).
