hey guys i recently picked up a spirit r/t several months and it ran good! The only thing not stock is the open DP. it made a difference, so i finaly put a 180 tstat new oil pan gasket and remove the blance shaft chain and switch to mobil one synthetic. After the work was done went for a ride and it definitely seems more sluggish. for instant i drop 3rd felt sluggish till about 5800 and all of a sudden pulled hard till 6500. Now it doesnt do that at all. sluggish all thru the power band. Any ideas?
