Hello. installed my G1 kit. very inconsistent boost. knew something was up. sometimes get good boost from a stop or very low speeds, get almost no boost rolling from higher speeds in higher gears when I WOT. barely beat an m x40i in a rolling race on the highway. that just isn't right for the G1 kit.
So I smoke tested the plenum. I found that there was a leak at the idle control hose, of course it's underneath everything. Would a leak at the idle control hose be responsible for the super inconsistent boost and loss of power that I am seeing?
Solution is to remove the plenum and reinsert/re-tighten the hose?
