It is NOT going to work correctly with the combo of parts(std chip).
I would NOT turn the boost up but be thankfull it has not done some damage yet, why would you want this to run correctly ?
The ONLY way this will run correct AFR is to have the chip changed or overwritten or change to the INJECTORS and MAP sesnsor that the(std) chip has been CALIBRATED FOR.
The point that jon@work was trying to mkae is it is suicidle to try to run this combo with std chip, he as I found it hard to beleive anyone would, or even expect it to work.
The "MIX" of parts must be right ie chip(settings) goes with certain injectors, map etc, you can't do pick + mix like in woolworths!!
You can of course have your chip rewritten on the oe chip with these bits, but would not advise changing the boost at all, just drive gently until it has been fixed, but it is your car, so turn away(boost) if so desired it can only go bang, and surely not worth it.
