Bought a 2006 330I. Running sluggish, need advice.

Hi.

I purchased a 2006 330I with 156,000KM (96K Miles,) and the car has a Dinan Exhaust, K&N intake filter (still charcoal filter there,) and has no codes.

The trouble that I'm having is that the engine feels sluggish before 4500 RPM, at wide open throttle. My old E46 330Ci which had less power could chirp second on every shift even when I sold it at twice the mileage, while this car just feels lazy.

It has plenty of torque so it's still nice to drive, but it has no punch in the lower end of the motor.

I have cleared all engine adaptations (using INPA) and it made no difference.
The cluster says it needs plugs in 4000km, but besides that is there something else that I should do?

My old e46 had a Vanos rebuild that sorted this issue out.

Ensure that the variable intake runner valving is working.

Be worth doing the plugs anyways if it's that close, real easy to do anyways.

Does your car have an automatic transmission?

If so, follow the auto adaptive transmission reset procedure, compare and report back.

I did oil as well as seafoamed the car and it's a bit better at rev matching but the problem remains. I'm definitely doing plugs soon!

The car is stick shift. I've reset all adaptations a million times using INPA.

Basically when you punch it in 2nd gear around 2,000RPM you really don't feel or hear much of anything until it gets to 4000+ then it sounds/feels like it should.
