BMW B58 engines are quickly becoming one of the best tuners engines. Check out all of our awesome B58 content including common B58 engine problems and building a 500+hp B58. We’re constantly adding new content for the BMW B58 3.0 inline-6, so be sure to check back!
Some were pessimistic about the B58’s tuning potential; especially after N55’s took a step down from the N54. Fortunately, the B58 has exceeded the expectations of many. There are already a handful of B58 engines pushing into the 700-800+whp range. It makes sense the B58 is progressing quickly given the N54 and N55 helped the…
The two predecessors to the B58, the N54 and N55, were notorious for busting chargepipes left and right. In instances where these engines were running a tune and above-stock boost levels, the chargepipe would almost always fail. One of the main reasons these chargepipes failed is that they were made out of plastic. The chargepipe…
When it comes to exhaust systems on turbocharged vehicles, specifically BMW turbo vehicles, everyone talks about the downpipe instead of the traditional cat-back system that people are most familiar with upgrading. That’s because cat-back exhaust systems and expensive and don’t really provide any power benefit. They sound great, but we’re bargain performance guys here! The…
Yes, the B58 engine does have an intercooler. However, it is not the common intercooler setup you would see on most turbo vehicles. While most forced induction engines use “direct” air-to-air cooling, the B58 intercooler uses an “indirect” water-to-air cooling system. The B58 intercooler is integrated into the intake manifold. Compressed air flows through the…
A lot of people cringe at the idea of a “cold-air” intake. Theory has it that a cold air intake has a bigger filter which lets in more particles which kills your engine life quicker. And that they don’t offer that much of a performance benefit. The first part about engine lifespan is blah blah….
While the phrase that something is “an art, not science” is used frequently, it does not hold true with turbo boost and tuning. Turbochargers, engine internals, and ancillarily engine support systems can only hold so much boost before they give in. We’re here to answer some frequently asked questions on B58 boost levels: How much…
What is the BMW MPPSK Package? The BMW MPPSK package stands for the “M-Performance Power and Sound Kit”. The kit is BMW-designed and manufactured and includes a more aggressive engine tune and a performance exhaust system to increase the performance, horsepower, and sound. The kit is only available for 40i models, featuring the B58 engine….
Following our general MHD post, we will now go more in-depth on B58 MHD tunes and expected power gains. Scroll down a bit if you’re only interested in the power gains. Otherwise, let’s quickly discuss some basic MHD B58 tuning concepts. About B58 MHD Flash Tunes MHD offers OTS (off the shelf) flash tunes for…
BMW’s B58 engine received quite a few important technical updates beginning in 2018. The new variant is dubbed the B58TU1. It is also available in “ML” and “OL” versions. ML represents the “middle output” 335hp version, while OL is the “high output” 382hp engine. Given the B58 is still a new engine, only time will…
BMW’s B58 began production in 2015 and was initially released in 2016 40i models. Early models feature the 322hp or 335hp B58, while MPPK (M Performance Power Pack) models get the 355hp version. Certain G series models began receiving the updated B58TU1 in 2019. The TU1 update is mostly intended to improve emissions. However, it…
MHD offers flash tunes for the turbo BMW N54, N55, S55, B58, and N13 engines. Their app is easy to use and makes tuning your BMW a breeze. However, the app is only available on android devices. Unfortunately, Apple prohibits the use of 3rd party USB cables, so iOS is out of luck (not completely)….
Ever since the twin-turbo N54 hit the market in the 2007 BMW 335i, BMW has been building on the design of the turbocharged, direct-injected inline 6 engine. In 2010, the 335i received the updated N55 engine followed by the B58 in 2016, however, the model was rebranded to the 340i. Unsurprisingly, the success of the…
