COBB would be nice since its a fast flash tune. Unfortunately it's only for the N54. OP has a 2011 that's the year N55 came out.

I have the PPK1 and I really enjoy it. It's no Procede or JB but it does give me piece of mind on warranty.
I'm waiting for COBB to have the flash for our N55's but I'm sure the F80 will be out by then and I'll take the plunge. Good luck.
