Lack of power, can't figure out why (Supercharged, EcuTek)
 

So yeah the car started doing this a few weeks ago.

I could feel that it had a tiny bit less of power, I thought it could be caused by the gas I used at that time but no.

Now the car just feel like stock... Between 1500-2000 to 4000 approx RPM it doesnt do shit. I have 286 whp (well had) and I know something is going wrong. Before you ask, I use Shell VPower (91) gas, since its the highest we have here.

I don't know a lot, so maybe someone could help me out and chime in.

At first I thought it could be related to my Borla UEL (Had a lot of issues with those), so I switched to JDL and same thing. Atleast I got better headers now.

Also, I noticed that I have a lot of black residue on my exhaust tips now, I never had anything like that before. I cleaned it and it came back pretty quick.

Here is a log from yesterday (Standard city / highway driving)

Thanks all !

Check to see if your intake hose is clamped down tight and everything else in the intake path. Check for leaks with a smoke test everywhere.

Also - there is some rubber hosing around the purge solenoid valve that might be loose.

Just a couple of ideas of easy to check ideas - good luck.

how much boost are you running with the SC? you might have a leak somewhere like the person above said

Im using the low boost pulley so around 9-10 psi I would say.

So you don't have a boost gauge? So that means you really have no idea what the SC is putting out.

Based on the sxs you describe, I would guess your sc is not actually pumping.

yea ......................................... a boost gauge would help.

Looking at your chart. You are not making any boost.
And you are getting some knock correction.

Boost leak anywhere? When I first had my kit installed the clamps werent all tight and you could feel the difference right away.
