Hi Guys,

I just thought I'd create a new thread because it's a bit off topic from the first thread I post.

Again I apologize to all the seniors if I am not posting on the right section and please excuse some of the questions that may seem stupid or repetitive.

The car is Stock 1999 GC8 WRX.

So there has been a slight change in plan, my ambition to modify the car with bigger Turbo, Intercooler, exhaust and all that might have to be put on hold due to personal circumstances. So What I am planning for this year is simply Boost controller (Done), Boost Gauge (Done) and Turbo Back Exhaust.

Turbo Smart Boost controller (the very basic T piece manual) had it clicked 9x from start and a genuine Defi Boost Gauge with the help of some senior members here pointing out the location for the hose.

So I test it few times over the weekend and last night and the boost gauge reading says 1.1 Bar at maximum and it just won't move any more after gunning it, my research on google indicates that it is equivalent to 16.4 PSI or there abouts.

Just wanted to know your opinion on what would be the maximum safe level for boost? I've research on forums and some say 17 and some say 19 before it hits fuel cut, there is just too many variant and I'm not sure which one is right.

Rang a few specialists shops, Maximum Motorsport says they wouldn't touch it and ask for proper tune which is $1650, S Technik said they recommend putting a STI ECU and leave the boost alone, Race Torque said the standard is 13 and you can boost it up to 17PSI, Another workshop in Cockburn (can't remember the name) said the standard is 11 PSI and you can boost it to 16PSI.

What would your recommendation be? I am happy with the current power setup and I've driven it yesterday and today in this setup (9 clicks at 1.1 Bar) but would this be a safe boost level? Bear in mind 60% of the time I drive it normally because of traffic and hours of driving etc that doesn't enable me to drive hard even if I wanted to.

Thanks so much guys and look forward to hear your expert opinions on this
