The only thing you have that will help generate power is the down pipes. 15/20hp. The rest is mostly cosmetic.

The one thing that surprised me was the loss in WHP after the first pull. I would have expected the FMIC to help maintain the power. I run a 5" ETS & its been very effective against heat soak.

yeah i was kinda shocked about that too...the 16 hp drop or whatever it was...i honestly think if i go again in ideal conditions 55 degrees and normal humidity...i can put down 340-350...but maybe im wrong

I think you need stage 3 for those numbers. If you watch that dinan video. His stage 3 car puts down ~320whp. You already have that.. I think the stage 3 flash plus you mods should give you ~340. I hope I'm wrong. Either way your car is running strong. Especially in 96 deg heat

At the end of the vid, steve says part deux installment will feature stage III with an upgraded compressor wheel matching n54 power...

That video made my day. Good to hear Dinan supports the idea that the N55 is a decent platform. Vargas had a modified wheel at Bimmerfest Saturday. Didn't get a chance to talk to them though. I'll be checking more into that.

You are above avg. for your numbers honestly.

Was there a fan in front of the intercooler?
Was the hood open for the runs?

I would wait for COBB to come out with something before changing over. The tune you have now is way too conservative. You just are not going to make any more power with that flash. It's all in the tune and you have the proper supporting mods. Call COBB up and light a fire under there ass. I am not a fan, at all, of piggy backs either...

You don't need a new wheel for your goals. You need a new tune.

I've tried both tunes and both cars are daily drivers. JB4 is n54 and Cobb is N55...Both have no issues in terms of codes and problems. Both cars no mods but tunes and JB4 destroys the cobb car each & everytime without even trying. The JB4 N54 car has more than double miles to date simply bcuz its more fun to drive.

No issues with both tunes...just matter of which u like better.

A flash tune like Cobb or Dinan has the boost mapped, meaning more mods does not equal more boost and you won't see much in the way of gains. So, if you are running 15lbs of boost by the dinnan tune and then add a bigger intercooler you will still be targeting 15lbs of boost and making pretty much the same power. More mods when you have a flash tune will not make more power, or at least not much. A piggy back tune will read the inputs and adjust to make more power but a flash tune is static. The car will due what the flash tune tells it to no matter if you have more mods than needed or not enough. In fact, if you change the car too much from what the flash tune was designed with your car will run worse. That means if you change mods on a flash tune you should adjust the tune to account for those mods. You have no way to adjust your dinnan tune so you should not venture far from the mods that the tune is designed with. That is why Cobb has different maps for different levels of modifications and Access Race Tunner to adjust them even more. With the mods listed, you would make more power with a JB4 or Procceds piggy back tunes. It is my opinion that Cobb is the only acceptable flash tune availiblle due to this need to customize static flash tunes. I know it is not available for your car just yet so you should keep in mind the limitations of the Dinnan tune. That tune is designed for a car that is different from yours, it will never be able to take advantage of your additional modifications.

And an N54 COBB will DESTROY an N55 JB car. What's your point? I've never had a JB car beat mine... and I've raced many...

apples to oranges here.

ur definitely right apples to oranges..
n54 obviously more potent.

My point being both tunes are solid and reliable and shouldnt be the decision maker.

true.

OP, look at what both can offer you plus what you expect in each of them too. then make a decision.

[cheshirecat79]

Opt for the JB4. I think the performance difference will help you get over the extra wires.

ive gone over this A LOT. but alas, it is n54 stuff and not exactly relevant to n55. n54 is def more tuneable, but n55 is still new...i hope it starts to break the numbers n54 guys have been putting down in a year or so.

all good opinions, i am not going to argue with any of your points of differentiation/positive/negatives. every tune has its benefits...but i do think cobb and jb4 are the most used/user friendly of those available...

ill re-hold my breath for cobb haha

100% agree with everything you said, just more hopeful than i should have been i guess

- you mean complain to dinan until they refund me?

You don't need a new wheel for your goals. You need a new tune.

BIG OL' UPDATE ON THIS:

JUST FOUND OUT, DINAN STAGE 2 WAS NEVER INSTALLED ON MY CAR...

F-That dealer HARD! 3 YEARS!!!!!!! I had paid for Dinan Stage 2! 3 YEARS!

Luckily a awesome, honest, hardworking tech at another dealer (YOU'LL NEVER READ THIS BUT YOU'RE THE MAN!!!!) noticed that stage 1 was present on the car during a reprogramming due to navigation/vanos/eccentric shaft/motor replacement last week....

Needless to say, both of us were shocked....that tech (angel) spent 5+ hours!!! trying to get Dinan Stage 2 flashed onto the car, after 4 freezes around 90%....angel-tech, stayed until 9PM! to finish my car, and get the proper flash on the DME.

THE MAN!

BIG DIFFERENCE!

most likely WILL NOT dyno it bc not really necessary...but hey, anyone looking for dinan stage 1 #'s, this is your thread
