which ones do i use to replace the stock boost pills (i threw mine away on accident). i was told #59 for both lines, by pettit. i dont see why they both would be the same size. but thats what i used. i just got my car back running after 2 mths of hard *** work. i added a dp while it was down and used the #59 in both lines. my boost built to 15lbs at half throttle. it my just be the added down pipe. other mods intake, exhaust.
i know i need an ecu but, im forced to wait for the aem...being i own an auto.

59 in both???? Nutts!!! 59 in the pre is the norm.

But in the Wastegate....NOT! 64 is normally in there.
Try 66 first and if you need more boost then maybe 64
depending on your mods.

best wishes jc.

 

yeah that makes more since, ill give a try.
thx, brad
