Having had a tune on this car (and off for warranty work) I could NOT drive a 335 without a tune. Night and day....

For example i would encounter random fluttering of the RPM's at stop lights, SES type lights flashing all the time, and sometimes the car just woundnt even start! So as soon as i got my 2008 BMW 335xi i told myself that i wasnt going to touch the engine, and that the car was quick enough....Now obviously im curious. Is it worth the risk??

Definetly get a tune. It transforms the car. Whether its the Cobb, JB4 or Procede your car will be a beast and since we've been tuning these cars for years without major incidence you can see its very safe, especially for tune only applications.

GIAC is extremely reliable and very smooth. I ran stage 1 for almost two years and have had stage 2 for the last year with zero problems related to the flash.

Coming from a VW, you should probably know how well-respected GIAC is with VW/Audi/Porsche and well-engineered their product is

good luck, you have many options, and lots of different opinions on this forum

"Should I tune it?". What kinda question is that? Thats a lot like having a hot girlfriend and asking "should I hit it". Of course you should. And if you don't, someone else will. So burn that rubber!

A flash, JB4 or Procede are wonderful tunes for the simple fact that the driveability of the car is not compromised. That level of refinement has been achieved.

I too am in the same boat...I reasearched these tunes for over a year, but after hearing how many people get turbo siren sounds, I have to be honest Im scared to damage my turbos.
How many of you running a tune hear the suren sound?
Please tell me:
Tune(how much boost)
Mileage
Have turbos ever been replaced?

There's like 3 people with siren sounds. Man up and put a damn tune on it Mama's boy.


Obviously, I'm playing about you being a mama's boy, since I know nothing about you. It would have been more appropriate to say that you are acting like a mama's boy.

The squirrel is on a roll today. No hard feelings...

That is insanely funny!!! Maddawg, you are the balls of a man!

If you think you will cry and bitch and moan when the dealer voids your warranty then don't tune. If you have no warranty well then......the answer is obvious.
