Default Maserati Ghibli JB4 Dyno Results! - 06-29-2018, 08:50 PM

Hey guys,

Been poking around with this 2014-2018 Maserati Ghibli project for awhile and finally was able to get it wrapped up and over to the dyno for testing. For those not in the loop it's a V6 3L twin turbo platform that retails in the 70k range. This specific car is a base model, and they also offer it in an S model that runs a little more boost from the factory. It's marketed to be an M3 competitor but realistically probably more like an Audi S4 or BMW 340i competitor at least on the performance end of the spectrum.

Our test car is a 2017 all stock base with around 13k miles on it. Also equipped with some huge power sapping 21" rims. Fuel was ~93 octane.

The JB4 is working great and we've already got CANbus up and running for advanced mapping, logging, and safety features. After a couple hours on the dyno we settled on a solid 50whp/50wtq mapping for the initial release. Probably another 15-20whp in it with more aggressive JB4 mapping as we get more familiar with the platform.

Intro pricing on the JB4 will be $529. We've got several units in stock and will be adding it to our website shortly!

Very nice... I've been considering an S for my next purchase. They sound great stock, but amazing with an exhaust. Plus I prefer 4 doors generally.

The tune is night and day difference even on just map 1. It was such a boring car compared to now. I'll try some mild e30 blend tonight and post some logs tomorrow on map 7. This tune is awesome!

I wonder what the '17+ Ghibli Grandsport S would put down?

I'd love to get one on a dyno and find out!

I joined the Ghibli Facebook group and a lot of people love the cars... But a lot of complaints too. I guess they are less reliable than our beloved BMWs lol.
