I got mine done at Cobb SoCal, just a modified 91 pump map (numbers from their Mustang dyno):
Stock (with bolt ons): 289rwhp and 313rwtq
OTS Stage2+Sport: 346rwhp and 407rwtq
Custom: 362rwhp and 428rwtq
I'd like to get an E85 map, but there is no station within 20 miles so it's not at the top of my list.
