X5M Tune
 
hey guys i havent posted in a while. currently have about 10,000 miles on the car now. no problems at all. not even the rockchips that everyone gets. anyway. . .im about to pull a triger on a tune. most likely a powerchip tune. anyone have experiences with this tune or any other tunes. also talked to a local x5m owner who also has a tune. he said to be careful with using LC. he told me his rear axle broke after launching the car with a tune (fixed at his own expense). is this true?

LC and axle breaks with a stock tune = warranty repair
LC and axle breaks with aftermarket tune = expensive repair at your expense, unless the tune is the Dinan one which comes with (theoretically) full warranty coverage.

That is the first broken axle I've heard about, though. They must be pretty stout to handle the stock power.

Broken half shaft also mentioned here:

Seems to be becoming more common on tuned 335 models as well as they push the envelope ever further.

While I agree with the formula that an aftermarket tune makes it an owner expense, you may get some argument from dealers that abuse caused the failure, even with no tune. Abuse always voids warranty, and it is a subjective determination.

You have some choices:

ESS
Active Autowerkes
Eurocharged
Dinan
Powerchip

I personally like Active Autowerks and EuroCharged, but any of the listed above are excellent companies.

Its unfortunate that none of them allow you to flash yourself.

I just bought a 135i with a dinan flash and every time the dealer wipes out your tune you have to bring it in for a reflash and they charge for labor.

Read the "it has begun" post.

I review the install and performance

Only thing untested is the 100 octane
