Performance chip: Snake oil or legit?

At the worst you'd be out 70 bucks. What do you guys think?

Literally impossible power gains from that company for a NA car.

Look at the Powerbox if anything.

Sounds good, I already have a sprint booster wire

Which I know doesn't increase HP, but the throttle response is absolutely snappier and noticeable, especially in the higher speeds and RPMs. Would this Powerbox be redundant to the sprint booster, or better/ worse? Does anyone have any experience with this item as to its effectiveness and not inducing error codes? The sprint booster is great and no codes so far, been using it for 6 months

This is why I'm here. Excellent honest advice from great BMW owners.

Thank you all- besides that PDF showing the installation and ECU / sensor fuss was enough to dissuade me. I'll stick to my Sprint Booster

+1, go with the BMS PBX if you feel like you need an upgrade.

The BMS PBX is a "real" tune (it increases power) while at the same time providing SprintBooster-like functionality, all via selectable "maps" of throttle response aggressiveness. Much better than the SprintBooster.

I think the dyne charge will cost him more than he spends on the product. For that keep it and don't dyno. Just search around to see if people got the results they where expecting.
