Hello big discussion here... N54 vs N55

_Jono_ · 11-22-2010, 08:18 PM

Will the new 2011 N55 twin scroll turbocharger in the 135i be tunable an reliable as the old N54? Because i know some ecu upgrades that send the N54 up 100whp. You guys think anything like thats possible in the new N55 coming in 2011 135i's? Are any companys gonna make any performance chips?

And one more question. Will the new competition rims on the 2011 M3's fit onto the 135i?

I would suggest the sub section for n54/n55 tuning. There are two threads on the first page about tuning the n55.

In short, however, yes it is tunable. Yes tunes are coming. And it doesn't seem to be clear yet if it is as tunable at the n54.

No idea about the wheels, but there is a tire/wheel sub-section too
