It hasn't been mentioned yet, but DINAN Stage II is an option. It is a software only upgrade for your 335is. And it will get you 385hp, and not void your BMW warranty. Down side of course is the price, $1799.

Then don't get a tune. The reason I say this is because getting a tune is like getting Carmine Electra in the same room with you and she gets naked and wants to boink but you got no protection....you'll be tempted to turn up the boost.

I've had both. Personally rather JB4. Best bet is to try one and if you dont' like it, return it and get your money back and try the other one.

Piggybacks don't tune the car, period. The make the dme misinterpret the signals they need to generate power.
You bought an expensive car, you can afford to do it right. That's all I'm gonna say.
Here come the fan boys...

OP, I have both and have tried both for tuning. I ended using COBB for tuning and JB4 for other cool features like gauge hijacking. Reason is all the of the above.
Go with COBB and don't look back

Has anyone actually dynoed this claim because the way the Dinan adds read it might be talking 385BHP not WHP. The reason I ask is I have not seen any tunes get to 385whp without either 100% race gas if all else is stock or Down Pipes and maybe another goodie or two on 93 octane.

If it is BHP then its only about 20whp over a stock 335is & a bit expensive for the gain.

It's BHP. $1,799 for around 50 BHP

335is is already over-boosted, there is only so much you can get out of a stock vehicle. 20WHP sounds about right.

If you want more out of it you will need more mods. 335is can use Cobb PROcede JB4 or Dinan to name a few.

OP, get with Jeff, he'll def point you in the right direction.

My baseline on a Dynojet was 314whp (Terry had guessed it would be around 310whp) & with only the JB4 Map2 ($505) it went up to 365whp. Have added the new 3/7 JB4 Firmware & the current N54_032512.HEX file which runs a custom 335IS Map 6 on 93+ fuel.

Don't know what the new WHP number would look like but the car with the additional boost is measurably quicker speed to distance over what it was.

Have a FMIC on the Brown Truck from you guys to be delivered on Tuesday. I am not really looking for more power from it (that would be nice though) but want to keep what I have from melting away in the Carolina summer.

If the normal 15% crank to rear wheels loss is valid I have 420BHP prior to the new maps & FMIC. Still think the major value of Dinan is the warranty which will cover what the BMW warranty will not.

The Dinan Stage II is 385 hp at crank, not whp. Depending on the dyno, your looking at about 320 whp and 360 wtq with the Dinan CAI and Free Flow Exhaust. Without those mods you looking at about 303-310 whp depending on temps.

Sorry for confusion I meant to say 20WHP from the Dinan sounded about right. 50WHP is a big jump for a tune only 335is car on pump gas. I would say thats the most someone could expect.

Thanks for your order, you will be happy with the FMIC for sure. Great consistency, throttle response, and overall power gains.

Either tune will work fine on the car and will give you the extra kick you're looking for. It ultimately comes down to whether your looking for a piggy back system or a flash tune for the car. As others have already mentioned, flashing the ECU/DME is the right way of doing things and that is the route I personally would go as well!
