i've got an 04 and i'm trying out the "dollar" or "bleed" mod. the way i do it is i put in a vacuum tee. one end to pressure source and one end to wastegate obviously. the other end i'm using vacuum caps with different size holes drilled in them. the bigger the hole, the higher the boost. simple enough. my question is: what is the highest boost you can go up to before the stock ecu starts pulling timing to compensate for the extra boost. the cap i'm using now has a hole about the size of a paper clip and i'm peaking at 17/18 and dropping off to 14/15. is this safe? thanks in advance.
