I have a 2011 335i with 69k miles on it. Currently running a MHD stage 2+ tune. I have been having some fueling issues, I went through 2 HPFP (remanufactured from FCPeuro). Just put a brand new oem HPFP in 2 weeks ago. I know i should be no where near the limit with the HPFP but am concerned.

Mod list:
New ignition coils / spark plugs NGK 1 step colder
VRSF metal charge pipe and turbo inlet pipe
Ingen cold air intake
Wagner performance 7.5” intercooler
VRSF high flow catted down pipe
Muffler swap to high flow and lighter weight
All pulleys replaced including vibration damper and serpentine belt
ECS performance coil-overs

I do not know if I should go with something like a fuel-it stage 2 to maybe help out the HPFP. I have attached a datalog below with a 3rd gear pull, my timing corrections have me concerned but are within 3 degrees so unsure.

Ideally I would like to focus on maintenance and rims/tires before getting ready for bigger turbos next year but my fueling situation makes me nervous. Any insights would be appreciated.

if you're not running e85, at your power / tune level you're fine.
Your fueling looks acceptable for an OTS tune
