Leaning out at 5500-6000rpm

verified userhey guys, just put my pulsar back to stock ( few bolt ons ) i have an hks front mount, hks BOV, 5zigen turbo back, hks intake and a boost controller few others nothing major. im running 1 bar and it runs good around 11-12/1 afr's but when it gets up to 5500 to 6000 it goes up to 13-14-15-16 and its sketchy i dont like it, so i changed the maf sensor, didint help. i checked my vaccum lines and they were all find as far as i can tell, i also did a leak down test and there wasnt any boost leaks ( even though a boost leak will make it run rich ) the only other thing i can think of is maybe the stock fuel pump cant handle 1 bar at that high rpm... my last pulsar had same bolt ons with a walbro 255 and it had no issues 11/1 afr's all across the board. I cant see the stock pump not being able to handle it but i will check it tomorrow, any other ideas or things to check/try would be greatly apreciated. thanks guys
Beat me once shame on me - Beat me twice, I turn my boost up :D

Maybe someone with more experience will chime in but I was under the impression that the stock fuel pump was inadequate for running higher boost. I'd like to run 1 bar this summer but I'll wait until I get a walbro 255.
pump first boost later, clean fuel filter helps too

get a walbro. its the best $150 you can spend.

I bought two for 100 bucks ea. Don't wait till your engine explodes from fuel starvation under boost.

b13 sentra or nx-2000 will work. use the factory strainer.
