Just installed jb4 and a dp, car feels pretty good but I am no expert when it comes to logs just want to see if everything seems good on them! Thanks guys!
Both logs I had to stop around 6k as I was running out of room but hopefully it’s enough to show anything bad.

Your HPFP was starting to crash. It's unusual to see at such a low boost level though. Other than that things look fine. Map 5 will start to introduce higher boost the more pulls you do since timing is higher on this run.

That is weird, wonder if there is an adjustment I can make on the user setting on jb4 to help the hpfp? Right now everything is set to default settings I got off n54tech

You can only slightly make an adjustment using your FOL. If the pump is crashing though this wont do anything. You should do a few more logs to make sure this wasn't an anomaly. If it continues to crash then you have an issue with either the LPFP or HPFP.

Will do more logs! Thank you sir!

Most of it looks good, like others mentioned the fuel pump pressure was starting to dip upon higher RPM load. If this is common across all the maps/runs you have done then you should look into the HPFP. But if the LPFP hasn't been changed then it's a good idea to take a look at that first since it can get clogged up with dirt, also fails commonly in the N55.

I have service paper that show hpfp has been changed within the last year, however I think the lpfp is probably still stock as I bought the car stock. It does have 88k on it so I will keep and eye out and see if I need to upgrade.

88k is too much, if the HPFP has been changed within the last year I'd go ahead and get the LPFP replaced.

To be clear the LPFP should flow more than enough for your current tune. I also wouldn't say that your mileage is the culprit but as I said before, your fuel system shouldn't be crashing on your current setup. If you decide to replace the LPFP then I would look into upgrading it.

Yea I was looking at some fuel it! Kits last night. Will
Have to add it to my todo list if it keeps happening. I don’t really plan on doing more power maybe just add a fmic to keep ait down some.

You should at some point plan to throw in some ethanol or race fuel. Even Boostane if you don't do it often. The first time I hit 18 psi on the stock turbo was the first time I felt like the car had any power.

I had a stage 2 vvt before this car and I liked it but for some reason this one I like better and it’s no where near as fast. It is kinda weird lol. I do miss the 500whp sometimes tho

I enjoy driving my X1 35i much more than the 335i I had so I know what you mean. I'll settle for 450awhp though, lol.

I had two evos few about 5 or so yrs ago and one of the only cars I regret selling especially my Evo X. Loved the power I had at 400awhp. It’s was perfect for a street car imo, you can have fun and not go overboard lol.

They are not as bad anymore. Or you can just do a delete. No worse then injectors,hpfp,water pump, etc on 335s lol

Here is another log I did today. Car started spinning really bad so I left off and went again.. on the hpfp is it if the number gets lower as rpms increase it means it’s crashing? I don’t feel any hesitation or anything pulls really strong all the way through..

When most cars hit 10 or lower the car will begin to break up. You may even see the fuel dump causing a black or dark gray smoke cloud out of your exhaust. Other than that the log looks pretty good. If I were you I would put 14 psi flat into map 6 and log that. You'll hold more boost up top than what map 5 is giving you.
