What did they charge you for a dyno run?

Did you ever do a stock baseline on pump gas? This thing definitely feels like it makes more than 382 hp stock at the crank according to my butt meter. Melbourne looks great!

No I havent but keep in mind load bearing dynos (mustang) are typically less than inertia based (dynojet). I think I saw one at 360 ish on a load bearing (car wow).

So 432 WHP and 408 TQ at 20.0 PSI - not bad!

I've read the rule-of-thumb is approximately a 7% increase in HP for each additional PSI, so if you hit the 22 PSI target of map 5 that may put you around 490 WHP

That would be awesome. Have to make sure the fueling will support it first. If that’s maxed out, then it doesn’t really matter. There’s only so much the JB4 can do. I’m going to do more data logging this week and have Burger figure it out, perhaps in Map 6.

Aside from an intake I have the same setup as you. Regardless what the numbers end up being this car is stupid-fast for the street.

Yup, the power delivery is so nice too. Easy to drive fast!
