i have to say the numbers do look, especially on a Mustang dyno. FWIW, when I dynoed mine fully stock (on a Dynojet), it yielded 280whp/283wtq. Going for another pull next month, will do Map 5 (all else stock), then Map 5 with exhaust (catless midpipe and axel back). Will be able to gauge the incremental increase due to JB3 and then the added hardware.
