1995 740il Bad acceleration

Hi, I recently acquired a 1995 740il 4.0L auto from a friend. The car starts, idles, runs and shifts fine. Can cruise in my neighborhood around 25mph fine but when I go to accelerate, WOT the car doesn't really move, kinda reminds me of the titantic. Big and slow. When I received the car it had a fuel pump issue so It would not stay running but I replaced that. I'm wondering if the fuel filter is clogged? Fuel injectors are clogged? Doubt it but cats could be clogged? I know about cars a decent bit but Bimmers drive me nuts. (im a VW guy )
Any help I would really appreciate it!

No one?

Check for vac leaks, fuel pressure, injectors

you're not getting responses because your question is insulting to those who choose to drive E38s. No offense intended- I'm being straightforward.

Answering your question objectively is nearly impossible. Acceleration is subjective. You may be asking too much of a very heavy car, despite its near 300 ft/lbs of torque. That said, a hot rod trans am driver (Wr6 or whatever) was once shamed when he thought he would run off and leave me.

Your symptom is too vague.

I did get a response thank you though for being forum police. No one said i was expecting spinning tires at wot in this car. I have a 400hp vw that does that fine. My question/help was 100% readable and answerable. Thats why war machine answered it way before you. No offense-intended . Btw war machine, i just bought a new fuel filter today and hopefully that will fix my issue.

Do not buy to cheap ofa brand, let me know how it turned out.

Going to pickup it up in a hour or so and going to try installing it. I heard it wasnt hard to do.

That was not my intent at all. I only meant that you should examine more the overall picture. I could laundry list typical issues that would prevent maximum oomph-- but that is much like just blindly throwing money at the problem. I'm not implying anyone else is suggesting that practice- only that for me personally to provide any real direction, more info is needed. Hope that makes better sense. I am in no race to answer questions, and after reviewing the thread- you didn't even follow his advice. Not sure why you assumed I was looking down my nose at you; I was not.

With that in mind, your problem is no doubt the result of reduced low pressure, retarded timing, lack of ignition /and / or weak spark, reduced combustion and / or compression, air / fuel mixture inefficiency, incorrect air density metering, intake air restriction, exhaust gas restriction... see my point?

I hope your fuel filter does fix the issue, but if it's clogged enough to really hamper WOT flogging the 17 year old car like a backdoor rug-- likely there are other issues that are contributing and / or helping mask other problems related to reduced performance. What is the MPG like city / hwy?

So what happened?
