So, i did a pull with my friend's m4. my car is n54 135 mt fbo with mhd v7 stage 2 +fmic 93oct map. walnut blasted and new plugs early this summer(less then 15k km) pull from 2nd gear up to 5th. by end of 5th gear my car went to limp mode, got a misfire code at cyl 4.

seems to have high timing correctly at cylinder 2 and 4
at 5686rpm in 5th gear, bank 1afr went lean to 15.5 and bank 2afr went lean to 23.7. fuel rail pressure also drop from 18xxpsi to 16xxpsi then fuel rail pressure when up to 2xxxpsi, but both afr stay lean. also, my timing seems to went to shit after i shift into 5th?

any idea what's wrong with the car? only seems to have problem in 5th gear.
i pm mhd, they seems to think i have leaking injectors in bank one base on my stft different between the banks.

thx for any help/input!
