You also may try this in order to gain some extra 0.1-0.15 bar. Some say "never touch your wastegate", which is a complete bullsh1t!!! It will not hurt your turbo, neither your engine, it will not crack (f.eg like the N75 valve does) and it can be reverted to its original position ANY TIME! I also have fiddled a lot with my wastegate and it did not solve my low power output (168BHP), but may add a few, not more than a maximum of 5-10 BHP, maybe just the amount you are missing. By adjusting the wastegate you are also changing the charasteristics of the power delivery though. Adjust the screws on the wastegate CLOSER to the actuator will increase boost (max 0.1-0.15, dont expect HUGE amount of increase) but at the same time, it will make the turbo to spool up slower (you'll probably lose bottom end torque). Adjusting it to the other direction, will decrease overall boost, but the turbo will spool up faster. Make your preference.
