No one said the Cobb wasn't faster. My issue is that I have not seen the gains expected nor seen by other folks with these cars & Cobb.

By the way, the fact that you didn't get a faster time yet had a 2mph increase in trap says you didn't launch as well. You should be 13.0 or 13.1. So it's 300 bucks for another 2-3 tenths plus another 2mph plus other features/reasons.
No, it is $800. That's about what a new AP sells for.

For the last time, we all know the Cobb does things the JB+ does not. That is not the point of this thread.

Well despite track times does the car feel faster on the road. I would be hard pressed to see a JB+ out run a Cobb stage 1

The Cobb has been on the car since Julystarting w/the map available at that time. I have since used 201, 202 & now 301. All had a decent amount of miles on them. I've not read about anyone having to rest the ECU to install the AP. The whole point of it is plug & play & be done in 5 minutes.

A coupe things that I would like to state;

1. An AWD car is notoriously hard to launch unless you have a DCT with some sort of beautiful launch control system ala Nissan GTR. It is very easy to bog an AWD car if you don't know what you're doing.

2. A 2 MPH improvement in trap speed definitely shows improvement but XI vehicles are not made for top end so don't expect any crazy differences in trap speed especially with tune solely. Go see what stock turbo evo's and sti's trap with tune only and you may be surprised; they are also a lot lighter.

3. A Cobb tune and JB+ are completely different and the drive ability of both is incomparable, if you don't see a difference in mid range punch and smoothness then something is wrong.

4. You can't judge a tune by one 1/4 mile run - that is absurd.

I fugured it would just turn into a flame fest w/the nut huggers coming out of the woodwork. If it keeps up I will just abandon the thread & have to think as you just said...just a hype machine.

For the last time, I've done everything everyone else on this forum says they do to cut great 60's.

Rain ruined the night. I will go back at a later date if I still have the car.

I maybe think the jb4 will beat a tuned cobb stage on pump gas..The jb4 was king on the street for years!!It has very good top end.Anyone race and jb4 fbo vs cobb stage 2??FRom claps vid the jb4 on map 2 is just as fast or faster.

Once again. Pick one argument or the other.

You say "it's not about tune vs tune", yet your entire post is based upon the fact the cobb "only" got you 2mph more trap for "$800". And if you're comparing one tune to the next, then the "cost" is the difference between the two, not the full price of the cobb.


So again, which complaint/argument do you want to use? If you want to talk about what you got for "$800" then the comparison is with a stock car. In which case you gained a hell of a lot more than "just 2mph" on the trap.

I'm not attacking anyone. I'm trying to understand where the OP is coming from, considering he keeps contradicting himself with everything.

And the jb4 is no more "proven" than the cobb? Are you conveniently overlooking the 1/4 mile times posted by cobb users?

Not happy that I only gained 2 MPH for almost $800 spent on the AP.

This isn't a Cobb tune vs [insert other tune here] thread.
This isn't a Cobb sucks thread.

I am simply stating the facts & hoping to get some answers from Cobb and/or the forum. This is an N54 335xi.

I do not have any logs of the runs.

You don't even provide time slips or logs, so how are people to help you?

What do you expect to happen when you created this thread?

Stop being a troll for this forum and post something of substance.
