Exhuast or fuel first?

I was all set to order my 190lph pump, 550cc injectors and SAFC2, then realized that I'm still on stock exhaust.
Should I get a full 3" exhaust first, then upgrade the fuel later? or can I still go with the fuel now on stock exhaust & 16g at stock boost
 
Stock boost is ok on stock exhaust. Any more and you will be choking it. You can order and install your fuel components now and get a base tune to learn how to use the afc but once you open the exhaust you will be tuning all over again.
 
I was going to post that you should do exhaust first, but I'm starting to second guess myself after seeing that you're running a 16G already. Fuel cut may get to be too aggravating soon, especially with a full 3" exhaust opening things up more.
 
Pump is already rewired, i'm going fuel first, exhaust will probably be a month or so down the road. I was hitting fuel cut @15psi, not running too bad at stock boost, besides some boost leaks. Not sure what it'd do with a fuell 3". Dah well, that'll come soon, then up to 20 LOL.
