I would swear I am making like 10-15 more horses also. Felt like the increase when I put on my UR pulley or my GReaddy PE. Anywhere in the middle of first gear I can mash the gas and the back end just moves all ove the place at will! Around 90 degree bends in second gear, will get way sideways at the exit under full power! Could judt be this was the first cool weekend in TX in 6 months, though!
