evo 5 reliable boost pressure

[KrazyieV]

Is running 1.2bar on my Evo 5 (155,000km in every good nick, no issues leaks, all parts up to date and quality oils etc.)okay?
Mods :
Sinco aftermarket exhaust manifold
Tial (8psi spring, thinks its 32mm) Vband Wastegate (plumbed in)
Full turbo back 3inch exhaust, cat-less
HKS SSQV Bov
Steel Intake and K&N filter
Walboro aftermarket fuel pump
HKS twin plate clutch
Apexi AVCR boost controller (tuned for a nice 1.2bar B setting and 1bar A setting boost) + boost gauge
Stock ECU

I live in NZ around quite nice cold air temps. Wondering if with my supporting mods it would be safe to run 17psi/1.2bar from anyone who has ran this setup before or any opinions or advice.
Thanks.

17Psi.... You pussy! You can easy run 20PSI while the weather is cool. You have a knock sensor system so Will protect it!

also do you happen to know if boost spikes (i.e it spiked too 1.5bar while i was trying to tune the apex boost-controller.) would damage the engine significantly .

If your engine fail's at boost spike at 1.5 then your engine was damaged before you started.
