I'm very unfamiliar with both companies and may end up upgrading to one later down the road. Does anyone have any experiences with either of the companies?

XDI is owned and ran by an ex-Bosch engineer so that's really cool. He's also worked with race teams. They also get another plus because their injectors are $200 cheaper than the nostrum and flow slightly more.

Nostrum is newer compared to XDI, and a bit more expensive. However, they have a lifetime warranty to back up their product. They even have a new and improved spray pattern that they show on their website for the injector. I could be wrong on this so please correct me if that's the case but I heard that the nostrum injectors require CVO adaptations to be turned off which would be done in the pulldown tab when selecting your upgraded injector or done by your tuner. My concern with that is the injectors will no longer compensate for flow over time if any conditions change. Is that even a real concern? maybe not.

Thanks in advance for any input. If these injectors are as cool as both companies make them out to be, it should be huge for the gen 1 community!

I recently installed Nostrum Stage 1. Great company to deal with. We'll see how they perform once the tune's dialed in. Doug has gotten another B58 to 675 whp on a DAW/Nostrum/DS2/E40 setup.
