So I've had my PS2 with stock fueling for the past 2 months and enjoy the additional power in the mid to high RPMs. Having boost hold all the way to redline makes the car so much more enjoyable over stock turbo. Rail pressure and Torque limiter was an early problem I encountered but thanks to XPH and MHD everything seems back on track. Realizing that the stock fueling will only take me so far I'm exploring other options for fueling...


So my goal is to run pump 93 only and hold about 20psi or more. I know upgrading the HPFP and LPFP will accomplish this but the price for XDI-35 pump is ridiculously high at the moment.


I do have access to E85 here in FL but would need a custom tune plus HPFP and LPFP to not stress the car out. I'd prefer to have the DME control everything instead of getting WMI, although they do have fail-safes.


Just looking for feedback and suggestion from others that have the PS2.


Here are some logs with my current setup:

if i was you i would go with xdi and E30 . you have easy access to the fuel .
xdi will provide enough fuel , as you have seen my b58 test couldnt do much with ethanol .

a m235i did 523hp and 770Nm on 100ron fuel
fbo PS2 car and xdi pump

Yeah the b58 pump looks like would be better paired to max out the stock turbo only

B58 pump and 18psi flat to redline on E20 with aggressive tune. "Maxing" a given setup is highly overrated.
