so i have a 93 luhrs 3800 tournament series with twin 671 ti's the problem is i get a lot black smoke and sometimes some unburnt fuel and/or oil out the exhaust. it is happening with both engines and since this has started i have had the fuel tank polished, changed the fuel/water separators, both of the air seps, and the fuel filters. it still wont climb higher than 1200 rpm's without blowing out tons of smoke and really seems to struggle to get up any further then that. also when its not under load i can easily get up to 1800 rpms with no smoke.
any ideas?????
