I have bought a used 2009 bmw e82 model. I was been told there is a leak in boost hose. I replace the part from ebay but still feeling sluggish. 1st and 2nd gear manages 2k+ rpm, but with pedal all the way down, the rest of the gears doesn't pull the car fast. May I know how to diagnose the issue.

    Welcome to the Forum

    How many miles are on the clock ? What is the general Condition ? These are indicators of where to begin looking.

    I would start with a Diagnostic scan to understand if there are any underlying control issues, what fault codes are stored? Next both the Inlet and exhaust side need close inspection 

    If you changed the Boost hose did you change both (one from the turbo the other to the inlet manifold) is the Inter cooler in good condition? Is the EGR valve clean and operating condition ? Is the Boost control sensor OK (Diagnostic should tell) Is the Turbo working correctly ? On the Inlet side no leaks all vacuum lines attached and in good condition?

    Hope this helps
