This page is dedicated to BMW Mod Guides. Guides range from 500+hp N54 bolt-ons, N54 port injection, S55 turbo guides, B58 downpipes, and plenty more. Check out all of the awesome BMW turbo engine performance content.
Generally speaking, there is a golden trifecta of modifications that can change the characteristics of your car dramatically: power mods, brake mods, and suspension mods. Of the three, suspension modifications are perhaps the most bang for your buck in terms of transforming money into enjoyment. This is true for most performance-oriented vehicles, F30 BMWs included….
Since the introduction of the BMW X SAV they have been fast selling models. The X3 was actually BMW’s best-selling model in the United States in 2019. Given the X3 is a popular car it makes sense that the X4 is a common comparison. BMW X3 vs X4 models share many similarities, but also have…
E36’s relatively small and lightweight nature can make them fun street or daily drivers. However, with these cars pushing 25+ years old, a few upgrades will go a long way in improving the handling and performance of them. One of the best performance upgrades is replacing the worn stock suspension with a set of coilovers….
BMW S65 V8 engines are in the 2008-2013 E90/E92 M3. This incredible 4.0L engine is able to rev well beyond 8,000 RPM’s and delivers 414 horsepower. Solid numbers for a NA V8 engine of the era. However, some may consider it a little lackluster by modern standards. Not a problem, though. Those looking to push…
The S58 3.0 inline-6 has already proven to be the most capable production turbo engine from BMW. It’s still a relatively new engine in the G80 M3 and G82 M4. Flash tunes aren’t even available yet, so this post may be a bit premature. However, we’re too excited about the future of the BMW S58…
Prior to this article we wrote a guide about N54 fueling limits and upgrades. However, we didn’t dive fully into port injection (PI) since there’s a lot that goes into these setups. Those familiar with the N54 platform likely have some idea about port injection. It’s the ultimate fueling solution for those looking to make…

BMW N54 engines have long been known to deliver great performance with a few basic bolt-on mods. Simple bolt-ons for the N54 can push the engine to 400-450+whp with relative ease. Downpipe (DP) upgrades are among the best mods to take the 3.0L twin turbo engine to the next level. In this guide, we compare…
Bootmod3 (bm3) is one of the most popular tunes in the BMW world for good reason. Pro Tuning Freaks bm3 offers a mobile app for simple flash tuning on the BMW S55 engine. They also offer a handful of off-the-shelf (OTS) flash maps with tons of awesome features. Those looking to tune their S55 should…
Finally, we’re getting around to writing about water methanol injection for the S55 M2, M3, and M4. WMI acts as additional fueling for the BMW S55, and also offers cooler intake temps. There are several other benefits to WMI that we’ll jump into in this guide. However, there are also a few risks when running…
The 2018+ F90 M5 is an absolutely insane car from top to bottom. It’s no secret the S63tu4 engine in the M5 is severely underrated from the factory. BMW quotes the F90 M5 competition model at 617 horsepower and 553 torque. In reality, this engine puts down about 620 horsepower and 600+ torque to the…
We finally wrote some methanol injection guides for the N54 and B58 engines a couple of months back. Now it’s time to show the N55 some love and discuss water-methanol injection. It’s an excellent source of fueling for the N55, and also helps the engine run cooler. There are, however, some risks to running meth…
