advice on boost level

[91tsi2wd]

So I have pretty much stock trim fuel right now, but I just bought an hks powerflow intake, and I'm planning on hacking the mass air, and Im going to rewire the fuel pump, my question is, what do you think is the new level of boost I should be able to run once these are both on? Take into consideration that I'm running 15 psi right now with no issues...and if it matters I have a 2.5" catback...thanks!

What turbo and do you have any other mods done? If your running the stock turbo I wouldnt go higher. The stock turbo will start to get out of its efficiency range.

I would say 15 psi is the max for stock fuel on a 14b. Race gas + fuel pump = 18 psi, but id have a datalogger to make sure everything is ok at that point.

Depends on your fuel setup. Do you have an upgraded fuel pump injectors and FPR. Also take into consideration, that with a stock SMIC anything after 16 psi all you are going to do is heatsoak your engine, I would invest into a efficient FMIC. I have heard of people running 20psi with a stock 14b but they have the fuel upgrades on their car to increase the boost to that level.
