I'm curious why and am about to go outside and do some lookin' around. Anything post turbo wont cause a decrease, but I've yet to mess with anything pre-turbo. :eek3: I'll be back soon with updates.
woot, with UP, DP, and catback I'm hitting almost 15 psi in 3rd gear WOT at around 3200 rpm . I like having this new gauge. What are you hitting alex? Craig
A DP leak wont cause low boost though, post turbo will only allow more air flow not decrease it. Which is why I believe it has to be a pre-turbo leak...if there's a leak. I just reset the ecu and took it out to play with it. It feels quicker, but I ran out of room to hit peak. I used both methods, the brakestand at 2700 for 5 seconds, and then also flooring it up a steep hill in 5th (most demanding load on the sti)...if I had more straight up hill I feellike I coulda squeeze a little more; however, I was getting like .095 mpa (roughly 13.78psi)...This is about stock boost, so I dont know what's up just yet. I want to yank out milo's delta dash and plug it in my car and see if I can figure out whats going on.
i need help too, i feel like i'm dying on power under boost. i don't know what it is and it only started like this since sat. i went through today and tightened up some bolts that have worked loose but it's still feeling rough. before i went and tightened, the car felt like it was dying at 5k or so. maybe the intake is making me run lean but it didn't feel it before. i need some help if anyone out there wants to go for a ride and give me a diagnosis
Sure, I'll be up at SoG wed. to get my front alignment checked and if we cant figure it out there, I will definately ask you for some assistance. Thanks bud
simple solution.....Engine Management... I went from 13 or 14 psi to 17+ when I got my accessport. "Poser Mobile says your outa pre-paid minutes yo!!!!"
Has it ever hit higher numbers? It could be just the weather or gas if it has. If not maybe the wastegate is bleeding it off too early. Does an 04 STi have the same setup as an 02 WRX? I had to adjust the arm on the controller for mine to hit full boost. Just tossing out an idea.
Hmm...After some research: Pretty much what I had already thought. As I mentioned earlier, after resetting the ecu I noticed a slight increase, but still seems low. I am gonna try it once again and get a buddy of mine to actually watch my gauge.
I thought the same with my car. I reset the ECu and hooked up my Cobb AP and used live boost and it was accurate. If you would like u can borrow my AP and we can use liveboost on your car. Let me know.
Might want to see if somebody can datalog the car and see what's going on. Maybe a leak between the intake and turbo inlet somewhere?
