please refer to my dyno results that performed yesterday on a Mustang Dyno. The values derived are well bellow what all other experienced in this forum. Note also the A/F ratio. Any help/comment is welcome.
My Unichip dealer said that I can go up to 12A/F without problem. This will gain about 30WHP. I am running with APS Plenum / Veilside Cat back System/100Octane Racing Fuel. Is it possible that the actual fuel is less per injector than anticipated? I am really confused. Note that this values derived with the stock Unichip setup. 356.2 WHP @6500RPM 336.6Ft-Lbs @4900RPM

 

those numbers are fine for an untuned unichip, but you dynoed on a mustang dyno which reads lower that what most of the people on this forum dyno on (Dyno jet). Mustang dyno usually read at least 10% lower than dyno jets. Get the car tuned and if you can throw it on a dyno jet just for chits and giggles to see what you get.
