We do not have a Chassis Dyno, but take all our cars to one in Pottstown. They work on Fords, are good guys and one of them owns a Buick that we work on. You can call them or us to schedule Dyno time... ... in south east Penn.
we are at 610-970-8944 (ESP Products)
610-326-7000 (Perf. Spec'ty)
Hope this helps,
John @ ESP Products
