So I did those tests didn't find any boost leaks but I just took apart all the hoses afterwards and tightened everything and it seemed like one of the hoses to the EBCS was loose so I took it off and put it back on (it wasn't actually loose in the first place it just looked like it), after this...

Ok Ill try those out hopefully nothings to broken

so my 07 speed 3 has a boost leak making only 13 psi, it usually makes like 19-20, and the fuel trims were very negative LTFT would sit at -20, and STFT would go +-25, I found that my turbo inlet has slipped off a bit so I put it back on. On startup, the trims were not perfect but they were...

ok is there a way I can test the injectors or would it be better if I just replaced them, also would you be able to recommend a brand or would OEM ones from NAPA be fine

Battery was disconnected for about 5 hours it did start at 0 and then it started going negative, the engine light disappeared but the code is still there Its also started running a bit lean AFR goes up to 15.1 sometimes and idles between 14.7-14.85. not sure what you mean by the maf but I didn't...

So I went to go check out this boost leak and I found that the hose connecting the intake to the turbo was basically off the turbo, I assumed that buddy before me was the one that did that so I took off the intercooler and reconnected all the pipes correctly, also checked exhaust side and there...

Oh ok I see ill just check the whole system

Ok where would you suggest I check, exhaust out and exhaust in of the turbo or the piping from the cold side(intake to turbo/ turbo to intercooler) or vacuum system?

Yea I have some logs, so you're saying I could have a turbo leak or maybe just a bad turbo? I checked my LTFT and it is at around -10 ish when cruising going as low as -20 and around 0 when I open the throttle more, also noticed that its gotten a bit slower

Yea it does it at idle itll go from like as low as -5 when it first starts up, and when Its just idling its usually fine but when I press the brakes I've seen it go up to like 5

yea its the drivers side of the intercooler, as for mods I'm pretty sure the guy just had oem parts put back in the motor he said the valves didn't damage any pistons and compression test was done and it was good, other than that its a catless straight pipe, cold air intake, and a Mishimoto...

heres the pictures

Hey, fellow speedsters I just got this car and it came with this code, Ive never owned a Mazda but I didn't think it would be a big deal, so I was looking into it and I found many possible solutions and Im not sure which one I should follow, It has a 91 octane stage 2 tune not sure what it is...
