Boost but no power
I have been running the FC on 10psi for a year now and everything has been fine. All of the sudden the other day I noticed the car losing all power under boost. I can still drive fine without boosting or boosting very little but once I get to 3-5+psi the power is all gone. I thought it was a leak even though I can see the gauge at a perfect 10psi and steady. I couldnt find anything then I thought that for some reason it might be leaning out too much at high boost so I even disconnected my boost controller. Now at 5psi stock boost it still does the same.
I searched it and it seems like im not the only one that has ever had this problem but there is no solutions out there. I dont have a wideband at the moment to be able to see if its a fuel issue which it seems like it could be.
Any idea?
Thanks

youre NOT running rich, if youre hitting your 10psi before your secondaries kick in you are lean. make sure youre secondaries are actually working 100% if you want to be able to use that extra boost before 4k id recommend going rtek, the 1.5 will work on stock injectors or you could go with a 1.7 and some 720s.
or im completely wrong, but im sure a guru will chime in here soon

Maybe I should have posted this before but I run an Rtek 1.7 with 720cc secondaries. Been running that for about two years with no issues and a full year on 10psi without a problem. This just started happening now.

Can you hear the turbo spooling? I have a similar issue with my car. Turbo spools up great but the car doesn't pull as hard as it should. It's because my tune is super rich. Pegging 9's rich...however i'm running a 60-1 with 720/1600cc's... get a wideband on there sir and see what she's doing.

Yeah the turbo spools great and boost gauge is reading what it should. I do need to get a wideband asap what I dont get is why would it do this now. I feel like it must be a sensor going out or my injectors crapping out.

Sure you don't have a leak? I had a similar issue years back, held boost steady but no power; turns out a few vac lines on my Profec-B had come off or had cracked. Which surprised me that it held boost and boosted to 11psi and held since the controller was apparently not controlling
