looks like 2005, 2006... Dang!
2005-2006 It's here ! Software to bring the power of your E90 325i up closer to the 330i (or your 525i closer to a 530i, or Z4 2.5 closer to a Z4 3.0) is now available. After all - your 325i engine is almost virtually identical to the 330 engine. Both 325 and 330 share the SAME 3.0 liter engine and internals. BUT the 325i came saddled with a more restrictive exhaust & catalytic converters, a single stage intake manifold (vs the 3-stage manifold of the 330i), and BMW's "detuned" engine computer. It's time to get that power back!
