You have a zhp right? I dyno'd mine last year. Got 210.5 and 196tq. on a "mustang dyno". 113k miles, stock dirty airbox, ss rep headers to 3" magnaflow. codes up the ass and 18x9 csl.
Since then I've flashed to euro software, (no cats or sap), and getting a new intake setup soon. I'll post new numbers when that happens.
