Boost pressure modefied new age STI
I have a question regarding the boost pressure on a STI new age (MY05).
I have a compnany in Sweden that will install Autronic plug n play box and some other goodies in my car this week. My question is, what boost pressure should they map in the car?
Is it safe to run 1.5 bar on every gear?
What does a Ecutek STI have in boost on each gear?
Regards

Yes I know,
But Instead of letting the car peak above 1.5 bar, I will go for a map that will have 1.5 at every gear. The stock turbo is of course to small for 1.5 bar in higher revs and it will slowly decrease in boost.

I was running 350bhp on my STI before changing the turbo; spec was APS TMIC, APS cold air, Walboro fuel pump, 3" turbo back exhaust, Ecutek remap.

Boost isn't the only limiting factor. The std ECU can cope with running a particular boost figure as it's got proper control of the ignition and runs it quite close to det (if it's mapped properly) but is able to sort itself out using it's adaptive learning strategies. A 3" exhaust will also give you boost creep at higher rpm so any ECU won't be able to reduce the boost as necessary to control the det either.
