I have a stock 2008 BMW 535i and I installed a Cobb last night to the stock aggressive stage 1 map using 93 octane gas. I can't say I really tell a huge difference. The install went good and no errors but I was wondering if through datalogging I can upload something for you guys to look at to make sure I am getting the most out of this Cobb. What options should I have chosen for the datalogging when doing so?

Maybe switching to linear instead of stock would help?

Kinda confused to be honest

 

I was looking at this after seeing some good reviews. I'm waiting to see how yours turns out. Did you contact the company directly? How is their customer support?

 

The Cobb is fun. If you can't feel a difference then you may have not installed correctly. You should notice an instant change, especially once you hit 3rd gear +. Plus its good on gas mileage because the turbo are working.
