Those of you running 335is, are any of you rocking a tune? It's getting to that point where I want some more power (car's feeling a bit sluggish lately, I wish there was a nearby dyno). However, I still have the CPO warranty and go to the dealer for everything including oil changes, so the thought of having to get into the ECU and remove a PROcede/JB4 each time kinda bothers me. Leaning toward the COBB at this point just for ease of use.
How much do you think I'm going to harm my car running a fairly conservative tune (hoping for 370hp-ish after an intake and tune)? I don't want to have to deal with blown turbos at 100K and I've seen people on here complaining about blown turbos. Is powertrain damage something I really need to worry about it, or is that something that only happens in the 450hp/meth injection range?
