Ok this is a bit of a long story so bear with me(it has been a year in the making...). I feel I need to explain everything in order to get to the root of this problem. With the mods I have on my truck I feel I have fairly low power and this was verifyed with a dyno run.
At W0T I have at 10ish psi at around 1500rpm(lots of black smoke), 15 psi boost @ 1800rpm(black smoke! engine still sounding like it's straining/lugging egts creep to near 900 post turbo(so 1200 right!?) if I let them), 17 psi at 2000rpm(engine note beginning to sound good egt's start to drop and smoke beginning to clear), 19psi at 2100 rpm
(engine sounds smooth no smoke).............. From here on up the boost climbs gradually to 30 psi at around 3000 rpm and smoke can rear its ugly head again a few more rpm higher(airflow limitations of the stock hx35 maybe?). The dyno concurrs with these figures with not about half available horsepower generated below 2000rpm and rising in a pretty flat line to max hp at around 3200rpm(ie 150 hp rising to 300 or so....) ...
Boost leaks have been checked twice in the last 12months, afc and starwheel were tweaked and all mods were done at BD power up here in Canada, fuel pressure was 22psi at idle(from bd's notes.... they said they checked it but didn't mention pressure at 2500rpm....??), bd pulled the injectors on my request and tested them and they came back good, the truck starts great always and runs fine though it hazes at startup/warmup a lot more than my buddies 98...
I have pulled and pushed as hard as I could on the waste gate actuator shaft with no movement(IS THE WASTE GATE STUCK?! or how else do I test as it was pretty awkward getting in there...???) and tomorrow I will take off the fuel shutoff solenoid to inspect it. My haynes says to test using the ignition with the negative terminals unhooked on the batteries???
I believe this issue has been there since I bought it though I didn't realize until I had all the mods done.
This is all I can think of right now. I'm a newbie with these trucks so be nice please
