I went to Coastal Dyno in Tampa. Everybody says great things about this shop, and I trust that he really knows what he is doing. He said his mustang dyno could give you the usual mustang numbers(lower than dyno jet) or he could adjust it to dynojet numbers. He mentioned something about mustang dyno's giving loaded numbers that were more accurate but lower. He recommended I go with the adjusted numbers, because that is what most dyno's give and would make for a better comparison.
