that can be a lot of extra weight back there, and unlike the new powerstrokes, we aren't running 50PSI of boost to roast the tires 
i would check your fuel filter and your timing. retarded timing can steal a lot of power - should have seen where mine started!!
with a properly set up IP, you should be able to get at least a bit of a haze out the exhaust when you really get on it. black smoke would mean more fuel than you have the air to use, clear exhaust means that if you give it more fuel, it'll be able to burn it.

130hp to the ground as n/a if everything is in fresh tune.hills + n/a idi = pedal floored pre-hill to keep momentum up.if you don't,speed falls off.the more weight you add,the more pre-hill speed,and lower gear you need.you'll get used to it........or you'll add a turbo.
theoretically remove the turbo and tune the modern diesel to run n/a and see how much better they fare.
don't be afraid of downshifting and feeding her the oil pre-hill.it's the way an n/a must be driven if you don't want speed to drop off so quickly.

who knows when they were last done, all I know is i got all new components ready to go on, just need weather and time, (and a timing light which no one in ontario has!). Im also willing to bet my timing is severly retarded because it just REEKS of diesel exhaust when standing behind the truck. My buddy with a truck just like mine was saying when he pulled that trailer with an 85 300sd on it he couldnt really feel it there, and never had to shift out of 5th (same gearing, and he even had 1" taller tires). The hills really arent hills at all on the freeway, but i guess with with an old fuel system, retarded timing and 3500+ lbs it would be enough to work her a bit. I wasnt afraid of downshifting and keeping her at 2500rpm, this way i keep the same pedal position, without lugging the engine and having to give it fuel

for your timing, either find someone with a meter, or just listen to it. it should have a noticeable "diesel clatter" pretty much all the time. if it doesn't, turn it up a little. i'm short on time at the moment, but there are plenty of threads around here on how to adjust it. just go a little at a time.

i know how to adjust it, just every says dont do it by ear because its tough. Will it run rough/clatter too much if i advance too much? like...it clatters, because its a fakin diesel lol, but its pretty smooth, more of just a bra bra bra bra bra. Should it sound more like cold advance?
edit: ill get a video tomorrow of it running and you guys can tell me if it sounds retarded

the cold advance sound is the "diesel clatter" we speak of, and you should have some of that sound all the time, but not as much as you do with the cold advance on.
too much timing will mean more clatter and less performance. too little timing will sound like a gasser and have less performance

Too much timing will hammer the heck out of your wrist pins and burn out glow plugs. My first crack at timing by ear netted me a bunch of burnt out Berus. I'm sure that after checking my latest attempt with a meter that my original tries had me over 14*. Once you get past the 8* recommended, any difference in sound gets to be pretty hard to detect.

is there an audible difference in sound between 6 and 8?

im not much better than Adam is without the meter/light on 'er.it's nice to know im not alone.
a few degrees either way isn't going to miraculously make the n/a not feel the 3,500 lb tow weight if that's what your hoping,sorry.that takes forced induction.

Spec is 8* +/- 2* so between 6 and 10 is okay. Most of the turbo guys like to keep around 6* to help decrease turbo lag (if any). I myself prefer the advanced side. I'm currently at 9*, spool up time isn't important to me and I've always seemed to have better cold starts with timing more advanced. I have no science to back that up but I have no problem making fire well below zero (farenheit) without the help of a block heater.
I really can't answer the whole sound between 6 and 8*. The only thing I can say for that is when timing a friend's truck, he was at 4* and we bumped it to 9 and I was shocked at how litttle I could notice a difference. Maybe my ears just aren't tuned for that. A meter is a must.

ive been following that supercharger thread closely. Although turbos sound sooooo good.

Retarded timing is generally better for power... I made more power at 6*BTDC than I did at 8.5... This advanced timing BS really has no merit, it never increases power, it simply makes it "feel" like it has more power by adjusting the powerband upwards... I have never made more power on the dyno with more timing... And I have spent quite a bit of time (relatively) on the dyno...
