09 135i n54 engine 83k kms, full bolt on, intercooler, charge pipe/bov and intake for mods. Also running a stage 3 flash tune from eurocharged tuning in Toronto.

So while driving on the highway in 6th gear between 2-3k rpms if I accelerate WOT I'm getting slight hesitations/misfiring. Sometimes I get an engine light and extreme rumbling under acceleration after that initial misfire. I never get the chance to get the code reading because the light goes away after a few minutes and goes back to normal. Not to mention my OBD2 reader is a piece of crap.

Second issue is after I retuned the vehicle after the intercooler and charge pipe/bov install, I've been getting running too lean code bank 2 on an engine light that comes on and off every couple days. Car runs normal other than some minor rough idling on cold start.

Spark plugs were replaced at about 50k kms, walnut blasting done at 60k kms.

Any help would be greatly appreciated, I'd rather diagnose the problem myself rather than get killed at a local shop with diagnostic and labour costs.

Need a log to diagnose anything. Could be a struggling fuel pump, or maybe injectors, but need to at least see your fuel pressures during the pull. Either way, your tuner should have seen these things. Is it a custom tune?

Shouldn't be seeing any problems with a custom tune. I'd give them a call first and foremost to let them know you're having trouble with it.

Otherwise, can you log?

That's probably a no then. You need to go back to eurocharged.

Alternatively, you get your money back and get flashed back to you stock bin. Then just buy MHD and a setup to run it, flash and log on your own and you'll be better off.
