01 7.3 sluggish and lower boost
I have a 2001 7.3 with afe intake, edge juice w/ attitude, 4" magnaflow straight exhaust. I has had a little leakage on the up pipes for a while, but recently the boost only gets to 15-16lbs where before it was 25-27 wot. Also check engine light comes on after 15 lbs of boost then truck seems sluggish. Not really any more power after about half throttle. But it would normally run Great when it was cold, after the engine warms up it never seems to have the same power/throttle response.
Tried unplugging the wastegate hose, no difference. Cleaned air filter, no difference. Scanned for codes and came up with none. Drove the truck got the light to come on. Rescanned and still no codes. Hose clamps are tight of the tubes. They also appear to be fine.
