I just installed the JB stage 1 tune on my n55.

Does it actually adapt over time? From a rolling stop, I find it slow before I feel any surge of power. I had the same tune on my n55 335 and it just felt very different.

I and waiting for the stage 2 upgrade to arrive but was just curious.

It does need time to adapt but you should of felt some increase right off the bat.

It actually took like 3 days before I actually noticed the difference.

I has stage one installed for a few weeks and was not impressed at all with the gains. I ended up returning it since I thought the risk of potentially voiding the warrant does not justify the alight gain in power. I've been waiting and hoping for some other company to come up with a flash tune.

Where did you get it from that they took it back?

what boost setting are you running? what fuel?

I am running 91. Not a lot of places have 94 around here though I can get it.

As for boost, no idea. How do I check that? I do have the USB cable... can I go in and increase it? If so, what is the highest level that will not blow up my turbos or slowly kill them?

I got it from http://www.bavauto.com/

I've been on the fence to try Stage 2 so I'm still waiting to see what the other guys have to say about it. Alan thinks it's about the same performance between Stage 1 & 2.

Some people have said that although the numbers might be similar on a dyno, stage 2 is better at reducing the turbo lag.

you need to download the interface and hook up the usb cable to your laptop.
best to look at the thread on N55 stage 1 on the BMS website for guidance around boost settings/octane.

I had a chance to give the car a good run today. The turbo lag is horrible. When I press the accelerator, not a lot happens then it surges. Stage one on my N55 335 E92 never did that.

I hope the stage 2 will make a big difference as it really sucks at the moment. Not happy !!!!

Are you driving in comfort?? I never have the lag issue and trust me I know the power of the N54's I had 3 cars powered by one and all were tuned.
I for one never drive the car in comfort, the car just doesn't feel like a BMW in that setting. Try it in Sport or sport+ and if you still have lag try resetting your tranny adaptation.

I never noticed any delay/lag even when my 2013 F10 was stock. Certainly not now tuned.

Now I am just guessing here, but I take it you do not follow the "advisertised" break in advise either?

Push the ignition button without your foot on the brake to wake up the car. Then hold down the gas pedal all the way down for 30 seconds. Let go and then start the car like normal. This should reset the transimission adaptation that the car has learned from your previous driving style.

Half and half. I let it stretch its legs every now and then. Now I give the car atleast one full throttle run once a day when I do drive it.

Usually drive in comfort sometimes sport. I'll try the tranny reset and wait patiently until my stage2 upgrade comes in.
