been curious about this lately,
I was just cruising back home last night and normally since stage1 reflash, my peak boost was 1.08bar down in the valley, then I was getting up to speed onto the highway in 4th at half throttle and I suddenly hit 1.11bar light nothing. I then slowed down and did WOT in 3rd and hit 1.18bar!
I was surprised. I drive an 07 WRX, stage1 and i'm pretty sure that's above target boost!
but then this morning I tried it again and only got to .98bar.
