Hello everyone, I'm looking into taking my B58 (specifically a G42 M240i) to a reliable Stage 2 tune and would appreciate insights from those with direct experience. Beyond the standard downpipe and intake, what are the community's recommendations for supporting modifications? I'm particularly interested in intercooler upgrades, charge pipe durability, and any fuel system considerations for E30 blends. Are there specific brands or configurations that offer the best balance of performance, reliability, and longevity? Also, for those daily driving, how has the overall drivability changed with these modifications? Any common pitfalls or unexpected issues to be aware of? Thanks in advance for the detailed feedback
