FS - Certificate for one full dyno run (3 pulls) at Curry's Auto Service in Chantilly. This is a chassis dyno, meaning that horsepower figures are at the wheels. I believe they have both a 4wd dyno and a 2wd dyno, but I could find that out. Most dyno sessions run about 100$/hr, I'll sell this for 50$ sent to you. Any questions? Carter
