From doing my research on alot of threads your setup with it lifted even with smaller tires is not going to get you near 10's I have seen bigger twins run only 800hp (maybe they wer not pushing the truck with alot pulse and a huge tune) but still you get my point. Plus with the lift I would guess you be somewhere in the mid elevens? Further readings have shown me the fast 10 second trucks have done lots of suspensions mods, different shocks, removing leaf springs, some have traction bars, clamoing the springs, bags, relocating shocks, etc. Not tyring to say a lifted truck cant do 10's and get your hopes up but your going to need more power or do suspension work. I would say run the setup do some suspension work and spray it. Sell the lift and use that money towards some shocks, and a nitrous system and I think the end result will be very positive and should not cost you anymore money.
