Hi Guys.
I am looking to give my car a slight boost increase via a Turbosmart Boost T. Car currently runs standard Boost (7.5psi). Does anyone have any knowledge of how much boost you can run before standard management/injectors etc can't hack it any more?? Someone told me 10psi, but that is effectivly a 33% increase, which sounds like it may be beyond the standard gear.
Car is a 84' dr30 with factory intercooler, hks filter and big exhaust.

Thanks for your help.

I used to run a turbosmart valve, on standard motor, injectors etc. it is a DR30 earlier model (82)
It was my daily and set it on 0.8 bar, no problems at all drove for years, never missed a beat.
Had exhaust and air filter - everything else 100% standard (no intercooler!)
Actually once i accidently cranked it right up to like 1.2 bar and went sweeeet and ran fine but then quickley changed it back - as fun as it was.
Have since got new computer and cooler with electronic boost control running bit more boost - still no problems.
I'm no expert but i would have thought 10psi would be fine.
