It shouldn't, I've actually turned mine 2 & 1/2 turns then backed down to 2 turns driving like that for several months. However, I don't reclommend going over 2 turns & definately suggest returning it back to stock setting prior to tuning as most tune flashes are based off stock setting therefore it would cause possible harm.

That would be 4 psi applied to wastegate actuator and then adjust the end link until it just fits over a closed wastegate operating arm.
It is important that you have a gauge that is accurate at that low pressure. If you get the base pressure setting too high the wastegate will not have enough opening travel and the boost will be unregulated, unregulated boost bends the stock rods readily in that situation. I know, I did it. I practiced the "if that helped that much I will adjust it some more!" against my better judgement. I had to pull engine and replace the whole rod set.
A safe thing would be to go back the two turns and then 1/2 turn more. This will give more initial boost but should not be so much as to put you in the danger zone.
so no problem.

I just wouldn't do it... Heard to many horror stories from people having oops's with this... Not to mention a lot of dealers are now hip to this little trick and are marking the wastegate bolt with special pens that glow under black light. I know it sounds pretty silly but its true. At least around my area. ;-) just save and get the 20lb reflash
