N54 Tuning Poll

Hi everyone.
I am considering an upgrade for my 35. It seems to me that it punches like a diesel until 4000rpm but beyond that isn't that exciting, just that amazing amazing engine sound. I believe that many of you might have done an ecu upgrade to begin with and I thought it would be useful to all of us to share our experiences.

1. MANUFACTURER?
2. HP - TQ FIGURES?
3. COST?
4. CHARACTER OF THE CONVERSION ? (f.e. is the gain analog to stock, does it get mad at high rpm, do you sense turbo lag, equally on entire band?)
5. DURABILITY OF THE POWER DISTRIBUTION?
6. ANY SIDEEFFECTS?
7. ERROR CODES?
8. DO YOU ENJOY IT?
9. DO YOU MISS ANYTHING FROM STOCK?
10. FUEL EFFICIENCY?
11. WOULD YOU DO THAT AGAIN?

Let's see what comes out.....
