Anyone have experience with ETG's tune for the 550? As I understand it, it's a slave ECU that's added to create about 80+hp, and is easy to take out of the car.

Thanks.

Agree on the N55, but I was referring to the N63

The gain on N55 is 61hp and 88 tq. I have the ETG tune in my f10 535i.

I'm not too sure about the 550, but the one on my 535i, it's awesome. You can definitely feel the difference. Especially the throttle response and reduced turbo lag.

ahh my bad
L7AS - how do you like the tune? did you ever have a JB3 you can compare it to? The numbers sound similar to Dinan's.

I love the tune! I can feel the car is more aggresive. Turbo lag is reduced significantly. I never get to dyno the car, but I think I will someday lol
However, it doesn't delete the CEL when changing downpipes and the other maps features that JB4 stage 2 has.

and nope, I never had the JB3. by the way, isn't it JB4 for the N55?

Jags also tuned my brother's X5 E70 and E92 M3. He's awesome and a cool guy!
