Seafoam lost top end! help!?

i used seafoam in my 97 dodge ram 1500 5.9l slt laramie 4x4. i slowly poured half in the main vac line and have yet to put other half in the gas tank, shut it off, waited 5 mins, turned it on let the smoke clear up, then test drove. when you floor it it revs to 2.5k rpm and bogs kinda then shifts instead of reving close to the redline and shifting perfect like it used to. but i can do a burnout when i couldnt before. so it bogs but i gained aLOT of torque. whats going on? be as specific as possible im not car illiterate ive been around them my whole life.
