328i Engine Tune Mods

Hi Guys/gals



I received my 328i about 3 weeks ago and have been loving it.



Now once I put a few more k's I was planning on getting a stage 1 tune.



Now I have been seeing "Drivetrain Malfunctions", "Engine Blow Ups", "Bent Rods". Like most things you only hear the bad. So far a stage one tune is putting me off



So what I would like to know from most of you is



1) What tune are you running and what stage

2) any other mods

3) Have you had a dyno done therefore what HP and Torque have you got

4) Have you had any issues

5) How long/k's have you put on the clock since the tune



Just some general questions, what is the limit to these motors/drivetrains.



I don't want M performance, I just want to be able to do 0-60 around a 335. Is this asking too much from my engine/drivetrain?



Thanks in advance
