Customer Reviews
Good product, quick ship
I ordered a Boîtier additionnel Diesel for my Peugeot. It arrived in about 5 days. Install was straightforward enough. Saw a noticeable difference in power right away.
Decent value, good performance
I was looking for a Boîtier additionnel for my Fiat Ducato and compared a few sites. Turboost System had a pretty good price during their "Soldes d'été" event. I picked up the unit for about 20% off. It felt like a solid deal. The delivery was standard, took 7 days. Installation wasn't too bad, and the performance boost is definitely there. For the price I paid, I'm happy with the purchase and the extra power.
Smooth order, helpful support
I bought the Boîtier additionnel Essence for my Audi. The ordering process was smooth, no issues there. Delivery took around a week to get to me. I had a question about the installation, so I used their online chat. The support person was pretty responsive and helped me figure it out. The unit works as advertised, fuel economy seems a bit better too.

Wondering if these boxes are legit or if I should just go with another brand like RaceChip. Anyone have experience with Turboost System?
Hey, thinking about grabbing one of these tuning boxes for my Audi. How long does shipping usually take to California?
