I was thinking to get Cobb Access Port.
Has anyone tried it on 535i?
Is it worth it?

Thanks.

I've heard good things about Cobb AP and Burger Tuning.

There aren't many tuners on the 5 series site, majority of people here focus on visual mods as opposed to engine modding and tuning. I recommend checking out e90post for these type of questions. Much more people tuning the N54 engine on their 335i, good place to get this type of info. JB4 is my favorite tune out there regarding JB4 vs. Cobb vs. Procede, although Cobb is probably the most user friendly tune.

Thank you for the inputs..

Reports on Cobb are almost universally positive. It clearly makes gobs of power on N54 engines. Above poster is correct, there's great info on E90post.com. I also recommend N54tech.com and bimmerboost.com for dedicated N54 engine tuning discussions.

Procede and meth injection for me . 400+ whp with all wheel drive

This may also be a good site to answer you questions.

Although I am a JB4 fan, I think N54tech.com is very JB4 biased for someone just trying to find info about certain tunes. If you don't know much a more non-biased forum is e90post, but yes N54tech is another good forum.

I've had the Cobb tune in my 535 for 5 months now and it is worth every penny.
It's a blast to drive.
Best part for me is that I can install and uninstall the tune from the drivers seat
and you don't even have to open the hood.
Sounds like the JB4 is also a great tune but I didn't want to mess with the computer.
