We took a Stock 2012 BOSS 302 Mustang and did a couple baseline pulls on the dyno and it made 367RWHP and 328RWTQ.
On a side note: We have a Mustang 1100-SE Loaded Dyno, which typically reads 5-7% less then a Dyno Jet. The only thing that matters are the gains over the baseline.
We then Installed a Magnaflow Off Road X-Pipe, Borla S-Type Catback Exhaust System, and a JLT Plastic Cold Air Intake to help the car breathe a little better.
No Mustang would be complete without loading one of our custom tunes for the 2012 BOSS 302 Mustang, which has a lot of changes made to the Ti-VCT to make up for the low end torque loss the BOSS has because of the Intake Manifold.
The end result was a Peak Gain of 33RWHP and 32RWTQ.
