Hey team,

I'm running E60 with the following mods:

VRSF ca.tle.ss d.own.pi.pes
Walbro 450 in tank (often referred to as stage 2 I think)
3.5bar TMAP
DCI
JB4 obviously

Using MAP6 I have been able to turn boost slowly up to 24psi and my fuel pressures are great (both high and low).

I'm wondering how far you can go boost wise on straight E85 with the factory HPFP. Does anyone know? Or does it vary car to car based on wear/mileage?

Curious what other's experiences are.
