So here's the story... I recently bought a totally stock 07 STi and I was having boost issues right off the bat. I was pushing only 13 lbs. I found out that the vacuum lines goin to the bcs had been switched. So i switched them back and bought a new stock BCS and then I was hitting full boost about 14-15 psi. After I started hitting full boost I flashed to stage 1 and I am still only hitting 14-15 psi. My car runs great, gets boost at low rpm's, and no check engine lights. I was wondering if maybe 15psi is all im gonna get or should I expect more? I know that the map notes say 16.5 but it also says depending on the conditions. I dont know if it matters but I live in Wisconsin.
I also was about to do some data logging when I noticed my AP said that my throttle % was 100 when I was only physically pushing down the throttle only about 50%. Is this normal or is my Throttle position Sensor messed up? Could this cause any of the problems I have been having?
Should I try to go to stage 2 to and see if i can push more boost. I was also wondering if i could flash to stage 2 with a downpipe and my stock cat-back exhaust?
