The 150 and 175 are exactly the same hardware. The 175 is the 150 with a factory tune. The engine has the same limitations whether it's a 150 or 175.
Peak power for the platform is limited by EGTs. We keep our EGTs sane. When comparing tunes, look at what the peak EGTs are and be sure that the EGT sensors are not skewed to report false low temps. Unfortunately with a black box tune, you won't know that till your turbo is cooked. Our VersaTuner tunes are unlocked, open, and editable by you.
We offer a bundle consisting of our VersaTuner software plus our VersaLink cable for $549 USD plus shipping. You only need to bring your own Windows tablet/laptop.
We ship from within the EU, so there should not be any import duty.
