I don't know if you still need compression test numbers but I had mine done at 120,000 miles and it was at 180psi for every cylinder. I the engine feels slugish I might think it could be the transmission. Not a problem with it, just how the ratios are, very tall gears. This car can go over 130mph in 3rd
