I agree but not for 100%. I agree with this: "[COLOR="Red"]I would suggest just enjoy the car, it's plenty fast and warranty is nice[/COLOR]". Car is really awesome, fast, enjoyable. At least for first year you could have 1000% of pleasure from stock vehicle and only after one year start to [SIZE="3"]THINK[/SIZE] about Stage1, Stage2..
Yeah that's also a great perspective, but I think people are lulled into a sense of security with tunes that actually never exists. They (BMW) will find out and you will have a massive bill, was it worth it for a couple of tenths off 0-60 maybe? I think if your going to tune your car really look at the possibility of blowing 10-15k to fix your car If it all goes wrong. Now are there some people who get away with it? Maybe but a lot don't and people say get a lawyer and this and that but by the time your done you have already paid 10k. Just be prepared for the worst case scenario any time you tune a car even if mild can cause serious issues to your vehicle.
This is why I usually stick with tuners who back it up with warranty
Yeah Dinan does they haven't released a tune yet have they?
No dinan tune just yet

I went with RaceChip GTS Black and also added the XLR.
They claim +88hp / 112Nm.
It´s a huge difference!

The Carbahn one looks legit but says it has to be installed by certified vendors only and not sure if there's one near me. Has matching warranty for $750 option

I LOVE it. Admittedly I have nothing to compare it to tune-wise. I posted my dyno chart a while ago

I'm guessing warranty w Carbahn is same as Dinan tune warranty?

It is 95% (or so) word for word - with the same list of benefits and the same list of exceptions and restrictions basically common across the two

I can second Mission Performance, especially with you being in the LA area. Alex has been a pleasure to work with and he's also located in LA.

I've had the stage 2 tune on my M340i from 1k to now 5k miles and it's night and day difference.
