Haven't tried it.

Seller claims 30% hp increase, 35% torque increase, 15% fuel consumption decrease, and longer engine life. All for a plug and play box that simply modifies the air/fuel ratio. And the same version fits different engines, such as the X3/X5, or X5 4.4/4.6. Wonderful.

That is patently absurd. Don't believe it for a minute.

I know anybody who claim such a gains for 150$ is crazy

why spend 10K on superchargers/turbos lol

but if somebody can take the flat spot that I have up to 4000RPM
im willing to try that

Hey, they included this HIGHLY detailed and obviously accurate graph:

How can you argue with that? Plus, they apparently have a warehouse with boxes stacked really high, a 911 on a dyno, some sort of workbench with a bunch of important-looking tools, AND there's a hot chick in a bikini that is clearly impressed by this product. Plenty of evidence regarding its effectiveness. HATERZ gonna hate, though.

the half naked chick is what sold me on the product!!...SMH its all EGAY GARBAGE not worth the money.

a dream is a wish your heart makes--- if only it was true. Looked for return policy, did not find. Slovenia???
