i have all the things in my sig on my car, at higher rpm, like 5500 and up my boost drops like 4 pounds... it will peak at about 12 or 13 right at about 4000 rmp and then above 5500 its drops slowly. why is it doing that? i have the 255 fuel pump but i was gunna wait until i upped the boost.... if i put it on now will it maybe do the trick???
the thing runs which is really all that matters but i wanna know wtf is going on...
i could use the help, thanks
