I have a 1994 Acura integra gsr. All internals are forged and no issues either he turbo (freshly rebuilt no shaft play). Up untill a few weeks ago the car was driving great and pulling really hard. I blew off a intercooler charge pipe twice and since re attaching I have lost all power. I have done a full leak test and found a major leak at one of my silicon joints and one small one at my air intake sensor. I fixed both and took the car for a spin and still no power. Car spools up just fine maybe quicker than before but Dosent pull at all. I have a wastegate mounted off my exhaust manifold seems to be working fine. The blow off valve is working too. At high rpms my air/fuel is up at 16 or 17, and with very little load at 2000 rpm I’m running lean at 12 untill I step on it . I can’t figure out where all my power went it’s like the car is making all the boost and dumping it somewhere. It’s somehow not making to the engine . Any idea. I don’t have a knock or any other issues. My catch can was smoking a bit after I parked but that’s all I’m seeing. Any advice is greatly appreciated 👍🏼
 
Stoich is 14.7
That is where most cars will want to run when just cruising around.
Under load, the AFR's should go down (richen up 10-11), after you let off the gas, the AFR's should go up (lean 16-22) then settle back to around stoich. If it isn't richening the mix under boost, then there is a problem just like I am fighting right now on my DSM.
 
on honda's i usually aim for 11.3 - 11.5 AFR with boost. what are you using to tune? Hondata?
