For a car large enough to accommodate four adults comfortably, there is a lot to be said for the F30.

With VW recently having announced a 10DCT, that age may soon be upon us. Even the 335d is pretty quick with a 6AT and much more efficient than a 335i.

Remember, not every event in daily driving...

If it is the same under square dimensions as the N54 and N55, and we do know it is turbo charged, not much reason to go beyond 7K RPM at all.

Ask people who drive those engines.

Ah, if only a polarizing filter were available.

Nice catch!

Maybe not if BMW goes I4 in a chassis designed to accommodate an I6.

Yes, that is good, but 8AT will be faster in acceleration.

If not 7DCT, then no M235i for me.

Nice, but one can only wonder what it makes on 91 and 93 pump octane gas with no methanol. Special fuel claims are not relevant for everyday non track experience.

The N55 intake valves are 1mm larger and valvetronic (which no one has really tuned yet) will add flexibility. The N55 will flow marginally better, at least until the exhaust manifold.

The...

And thus potentially more rewarding. I am not aware of any tune that alters the OEM programming yet.

I would say a little optimistic.

Can't go wrong with that. They will crack the OBD II port encryption scheme then it will be all fun and games without fault codes.

Save for a FMIC and upper CP, regardless.

Yep, different tires with different slippage will give different readings.

But controlled simultaneous baselines is fundamental to understanding modification results. Why Cobb only quotes...

Just service, preventative maintenance, warranty work and the occasional recall. My dealer is very thorough (#13 nationally) and will usually scan the car electronically and visually to check for...

Cobb uses a very conservatively set up Mustang dynamometer. That aside, they express the relative gains in percentages over the previous tune at their website so the great web believers society does...

Presumably every time it goes in to their shop.

I bet you mean graphical charts of dynamometer readings plotting torque vs. rpm.

Yes, so ready. One more year of warranty.

Sears sells several and ships quickly. You will need an E14 reverse Torx socket to remove the center bolt on the firewall.

I now need an LSD.

Brave new world.

Quickest race will be to the next E85 station for a refill before the tank runs dry.

He will beat most of the old Turbo Supras.

The VMR wheels do seem to be a "soft" gravity casting. Anyone have them? Are they made in China? I have my suspicions.

Here it is if you have the early DME. No failure in field seen yet, but best to have BMW update your DME before first upload.



Email Josh if you have one of the old DME specified.

For the USA. Some other markets had them in 2010 MY.

Actually the N55 in the F30 is both MAF and MAP.

Well, that is certainly no longer true!

Steptronic display had me confused for a minute.
