Yet another Gernby etune success

Whose car? Mine has a 63.5mm Berk high flow cat and Tanabe Medalion Touring dual exhaust. 221hp at the rear wheels on a Mustang dyno and Gernby FlashPRO tune. Significantly more mid-range power.

The issue is although the stock cat flows very well, resonant frequencies exist with its design that result in negative performance changes when trying to lower vtec rpm. You lose power instead of gaining. A hfc, as well as a tp, have different resonances, and don't counteract lower vtec engagement. You can lower vtec effectively and improve power under the curve.
Basically, with the stock cat there is no point in Flashpro.
