Yep IIRC that was it.. Pretty much everything barring exhaust upgrades from the header back, cams and csl style airbox and alpha n tune.
So the true baseline would be something around 300 as a lot of that stuff is just reinstating back to stock level.

Good stuff Bimmerfan, only proper way to know if you’ve actually made improvement. What are your planned mods?

For comparison this is the same dyno my SSV1, 300 cell GESI cats, and carbon airbox put down 331. Obviously a different car but still an interesting data point.

Nice man, looks about right for a healthy stock S54...obviously the high mileage doesn't seem to be hurting performance.

Just got a fresh tune, big thanks to Jordan RK tunes. Izzy IMG and Big thanks to the M3 community that keep pushing this platform, ie the duel 2.5 in X pipe.
This is my 3.5L 12-1cr stroker at 9 years old and 18000 miles

Based on his post, pretty sure it's an S54 stroked out to 3.5L with high 12:1 compression pistons

AKA.. my pipe dream
