wow these trucks can PULL....
i had to tow home my moms car from waipahu, its a 1996 impala ss and weighs 4400lbs. the 'hillbilly limousine' weighs in at 9300lbs ( due to the 2000lbs + of tow equipment in the back...) and i got diverted over red hill on the way home due to road construction, its a steep one. only about 1/2 mile but really steep ( i think its like a 6% grade ), almost every car drops a gear to pull it, but even at a combined weight around 14000lbs, she pulled the impala all the way up and over in 3rd gear ( i never use o/d when towing ), 2300 rpm, about 45-47 mph bellowing like hell out the dual 3" stacks and just rolling coal the whole way ( cars behind were slowing down cause they couldnt see or they thought i was on fire hah hah hah....). i hate that i gotta close my biz at the end of the year and go find a 'regular' job. dammit. love this old p.o.s. redneck cadillac. it has had its share of problems ( almost all fuel related ) and she knocks like a jackhammer on crack, but BOY can she get the job done. yeehaw.

you need to check the air filter,and or turn down the fuel.
rolling coal looks cool to some,but doesn't actually add any power at all.of course there is our kids to think about too lol.but seriously,you can hurt the rings etc.
she'll pull that load all day long without effort and smoke free.you wont notice any power loss.
i thought you used to tow all the time?

yes i tow all the time but usually not such a heavy car and not over red hill. i was impressed to say the least. i drive this thing all the time but you dont really feel that power till you get into the throttle a bit so its decieving as a daily 'normal' driver. till you put your foot in it, that is. thanks for the advice i will take a look at my ip allen screw when i get the chance. i think im supposed to ony go 1-2 flats at a time if i remember....might help if i cleaned the cdr too, i think im going on 5000 miles without cleaning it.

oh yeah,you have to set a few ton behind her or on her and hit some hills to feel the grunt.i see 2nd on the hills with the E40D loaded up pulling some real grades here in Maine all the time.no turbo needed,but wanted lol.
our speed limits on most rural roads is only 45mph,so iv got no trouble here really.
driving empty,you don't get to feel her grunt,or listen to her talk nice under load.......oooo boy that's a nice tone.that's when you know you have a diesel.

I love having 3-4000 lbs in the back going up a good 10-15% grade, she roars pretty good but keeps a steady 80km/h the entire way, and lurches forward trying to race as soon as you get to the top.

As far as turning the IP up. I believe i noticed in another post that you have a banks turbo so ill start there, iirc rule of thumb is one flat, ideally you would want a light haze of smoke at WOT under load. On non-turbo engines, 1 flat is usually more than enough to smoke, as was the case with mine at least. I think we eneded up at around 4 flats with our ATS, not 100% sure.

I cranked my pump and with the dual exhaust header set up I could get up to 1200 degrees f pretty quick if I did not watch it and I would rolling coal pulling a load. I would have to let off even though I was getting more power because of the high egts I was seeing. I would think if you are over fueling it then you would see lower egts. That I would think would hurt the rings. I know aluminum pistons start melting at 1200 degrees f and are liquid at 1400 degrees f. From my experience a pyrometer is a great tool to have when turning the pump up. That way you know what is going on air/fuel wise.

yeah,thats why i haven't turned my fuel up yet.
i didn't see any smoke at all under load while WOT.since then iv opened up exhaust and air intake.i bet i have a little more grunt there,but don't dare touch it without the pyro first.

Well if you can and will watch your exaust a pyro isnt 100% necessary. If your not overfueling, your egts wont be excesive. So technically you can turn the pump up 10 flats if you wanted, just dont MAKE it smoke, thats why the skinny pedal has a spring

i usually dont have smoke till i put a load on it or get into the loud pedal about 1/2 way. and my pyrometer said i was pulling 930 degrees when i was almost to the top of the hill ( it used to pull 1000 unloaded, but since the dual 3" stacks and glasspack mufflers it has dropped egt significantly and got more power / better mileage to boot. ) now my "normal" around town unloaded temp seems to be between 325-400 degrees...as long as i dont moosh the throttle, just drive like a little old lady. a 6 foot 2, 300lb, fat, sweaty, grouchy, and slightly unattractive old lady with a shaved head in my case.
