a few months and many KM... and it's been daily driven at that psi ever since it was tuned for it as there is only a single stage boost controller connected.
Although that will change very soon... we're going to put a stronger WG spring in for base pressure and change the coil packs to new DFU's from Electromotive (GM coils). That should let us go further up in boost w/ some race fuel or maybe even W/I.
So first stage boost will probably be anywhere from 12-15 psi and 2nd stage 21 psi (or more with W/I
)
