fuel pressure regulator for cheap turbo.
I am more familiar with sc/na setups, thinking of building a cheap mid mount turbo setup good for 2-3 pounds of boost. Im thinking the stock ecu will compensate for fuel since boost will be set very low. I was thinking if anything i could use a FPR if wideband says im running lean. Low Boost would make the same amount and maybe more, rather then spend tons of money on headers exhaust intake and some kind of piggyback.

I know in the past that people used rising-rate FPRs to compensate, however nowadays with the availability of aftermarket ecus/piggybacks being so accessible I haven't seen them being used as much... It'd be best to ask some of the SC'd guys how they're ECUs handle boost (and at what psi they're running) as normally the ecu is able to compensate up to a certain amount. However, if that's the route you plan on taking then it'd be in your best interests to invest in a piggyback anyway.
