agreed, did not know u was only running a piggy back style ecu go for a pfc they cheap and will handle everything you need. but in general would it hurt to add a couple of psi? i'm only running 10psi off the gate no boost controller at all, i have a manual boost controller..can it hurt to add a few psi? i have an apexi turbo timer which shows hypothetical afr's and mine is always in 10-12 range (meaning lots of fuel yea?) so can it hurt to add some psi?

p.s sorry for hijack!
