Course Frequently Asked Questions

Common questions about our B48 mod course.

This course is going to give you a foundational understanding of performance upgrades and tuning for the B48 engine. We cover each modification in-depth, providing knowledge around the performance benefits along with important considerations to help you choose the best options for your setup. We teach you what you need to build a 350whp+ B48, but do note this isn’t a 100% done-for-you solution meaning we aren’t going to tell you exactly what you should do but rather give you all the information you need to make an informed decision yourself.

From a tuning standpoint we cover everything from JB4’s with BEF’s, to MHD/BM3, custom tuning and so on but this course is not a DIY-tuning course, so no, this will not teach you how to custom tune your B48. We suggest leaving that to the actual custom tuners.
