So this might sound like a stupid question but I was curious if it was possible to get the over boost function that the 335is has where in the first 7 seconds hits 370ft/tq on take off.. I was wondering is this possible to get on a regular 2007 335i coupe? Will the jb4 g5 give me this feeling? Thanks

why do you only want the extra boost the first 7 seconds, why not always?

ya, any tune will give you unlimited "overboot"

Well I want it all the time, my question is, will it give me that sudden take off like the 335is? I do have an auto tranny donno if that matters.. And the 335is in order to get the over boost function they added crazy air vents and fans and all that stuff to help cool it down since its runnin all that boost. Wouldn't I need all that stuff to? In order to be safe enough to handle the tune... Thanks for your input guys.

JB4 or Procede will give you that much power or more full time. No other parts necessary.

Just get a power kit for the other added benefits that a 335is has

Power kit is not the same software. The 335is has different base software with a different ignition curve more suitable to higher boost.

My 135is runs the PPK-2 power kit as factory standard & stock for stock the 335is is stronger.

This is what I'm talking about.. Wouldn't it be possible to use the 335is software on a 335i? Given in practically a factory tune that is probably considered the safest out there

Yes, you can if you have a Cobb PTF @Dzenno and @Jake they can make a map just for that, and I am sure Terry must have a map that simulates it as well.

And the extra cooling features on my 335is, isn't just for the over boost, it also takes care of other things as well.

Ya I feel that if I do the tune and don't have those cooling features it might be bad for the car, what exactly are the cooling features you speak about?

The 335is has the better far for the rad (850 watts), the two coolers in both wheel wells, cooling vents, software to control it and Ivo found some more differences but I can't remember what they were. I also had the AR oil cooler on my old 335i and it did make a difference in the temp, but since the 335is has two of them I sold it.

Running a tune isn't bad for the car, as long a s you run a good, well-tested tune. Shiv's car has been tuned since he bought it and now has 700+HP to the wheels, And I think he's over 100K miles now...

true but it doenst mean hes never had a problem and when he does have one he made the tune software/hardware he can easily fix it unlike most if us reaching out 4 help for the most part.

can anyone list the mechanical differences between 335i and 335is other than the exterior Mtech kit or the obvious?

I think engine wise it has a better radiator, bigger oil cooler, and stiffer engine mounts.

[yomny]

The car has a heavy duty radiator fan for improved cooling, an additional smaller radiator on the drivers side front air dam(replacing fog lamps) and the improved oil cooler on the passenger side. Aside from that, the tune which as mentioned above is improved in all aspects, not just an over boost function.
To answer the initial question, the only way to get the function of the 335is is to tune your 335i but it wont ever have a temporary over boost function, that's only bmw's software, I could be wrong. You could get a tune and improve timing and air fuel along with more boost. I think bmw has proven that its safe and reliable to run 14 psi on these cars all day given that cooling is sufficient.

I think that is correct. they basically took a page out of the Dinan tune handbook based on their stage 3 tune data history, running at 14psi w/ ancillary OC, IC and exhaust. Pull on it all day w/o worries.

I don't think so. Terry's firmware takes advantage of the factory software does not replace it. He runs two different firmware versions for the 335i & 335IS

So if I get a better intercooler and a better oil cooler, and get a mtech front bumper do the fog delete for vents then I'm ok?

you don't even need the bumper, even just an oil cooler would be fine, but then again I wouldn't advise anyone against upgrading the FMIC. The stock unit is garbage compared to even the cheap aftermarket offerings.

[ttbmer]

so the mark up 4 335is is just on the cooling and cosmetic looks?

Yes, and the DCT if you're into that kinda thing.
People who own one will of course tell you it's the rarest type of E92/93 but how much does that matter IDK, still a mass produced model..

what makes the stock unit such a piece of garbage?
