Taking my car to the dyno tomorrow, TI Dyno in Ashtabula, OH. I've been losing MPH the past few years at the dragstrip and thought it might be good to see if a pro can coax some of my power back. I used to trap 107-108, even hit 109 in perfect air. Anymore, Im barely hitting 106. I did upgrade the valve springs this past winter, complete new exhaust from headers to tailpipes (now 3" w/ Xpipe), COP ignition. Should be fun!
