true plug and play tune offering safe and adjustable 25-70whp gains. Can be installed and removed in minutes without any tools.

At the default setting of +2.75psi average increases are 40hp and 50tq to the wheels. For those looking to take things to the max up to +4.75psi can be quickly dialed in! Does not trigger codes and does not require entering the ECU area for installation. Compatible with all ECU versions and transmissions for BMW 135, 335, 535, X6 and Z4.

Sold my car. Use it for 1 yr. Great gain. I had it on my 335.

Asking $180.00
