That’s pretty phenomenal for how few mods you have listed. In fact it’s so different from a lot of the dyno sheets I’ve seen that I have to wonder if their dyno is out of calibration. Here’s a dyno plot of a stock 05 Mustang 4.0, as found on K&N’s site. It’s fairly typical for stock, though the K&N plot may be a tad low, possibly due to the 29.00 barometric pressure. Picking up nearly 50 HP compared to the K&N plot from just a CAI and dual exhaust is a bit surprising though. The A/F ratio seems a little rich too for a NA engine. Granted there will be variation due to different dynos, cars, and weather, but still …
