Default fuel fuel fuel...less of it??

My 96 has been together for a couple months now. Its only had less than a hundred miles on it but it runs great. I was geared more for performance but after having to tow i dont want to do a whole lot more to it. Its got a brand new 180 pump with 4 kgsk, stock dv's and a #6 plate, SDX 5x12's, AD II 165 and a new industrial 62/65/12. I wanted to do compounds later on down the road but now i just wanna drive it. The biggest load behind it was a 26ft tilt bed and a large frame skid. It pulled it just fine but it could get a little smokey if your not light on the pedal. I dont know where the plate is set because it was installed by industrial and im pretty sure the afc is stock. My question is, can i set the afc for full fuel at 30 or more psi and that take care of the lower rpm smokeyness? Or do i need to ditch the #6 for a way less aggressive plate?
Thanks guys!

you can pull some of the bottem end smoke out of it with a good AFC tune but it will always be smokey pulling a 26ft trailer and you will loose a little grunt off the bottom aswell if your arnt heavily fueled to start with, nature of the beast. your set-up sounds pretty good. good turbo size nice size injectors and my favorite plate. do you have a good intake/filter and 4 inch exhaust?

It can all come down to your skinny pedal... i just use my mirror and get light on it if i intend on towing, but i get what you mean.... my trick is to let it breathe if going uphill... rev 2000rpm no matter what i'm towing...

Good stuff thats input i was looking for! All i have for a intake is a BHAF. Also running the stock intake horn. It does have 4 inch exhaust too. Im a little gun shy when it comes to messing with the afc, but i'll try it. I guess if i feel like i lost to much low end grunt i can always turn it back. I do like the #6 plate to, it just makes me pay a bit more attention when towing. Would towing compounds be the best option for egt control? I like the set up but i feel like im constantly watching my egt gauge when towing. I would like to not have to worry as much about it but maybe im just paranoid because its a brand new motor.

Twins will definately work, but a larger more efficient turbo should also work if twins are too pricey. Sounds to me like ya need to stuff more air into it.

Compounds arent out of the question. I would like to find a s471 and build my own.

for what you are describing compounds are not needed at all. compounds are for guys that want to street 600 hp and occasionally pull a trailer. up to somewhere just north of 500hp is totally doable with a decent size single and you can still use the truck for what it was ment to do.
