Looking to get a tune for my 535i xdrive. deciding between JB4 and ESS tune. Any opinions on whats better/worse? the pros and cons? my car is a daily driver. i dont track. just looking to have highest power output when i feel like having some fun. dont really have any mods on the car. looking to get a meisterschaft exhaust muffler only. anyone have experience with both? thanks in advance.

Check out the COBB unit. Unlike all other tunes (exception of piggyback unit), you can uninstall and resell the unit...plus you can DIY and it's just PNP thru OBDII port, and it's an actual flash, so you retain all the processing power of the OEM ECU.

Does the COBB unit trip CELs? If so, can it delete them such that the dealer has no idea that the unit was installed?

I just installed the jb4 and I love it! I have a stock 535 so in same boat as you are. I plan to add an exhaust soon but that will about it.

Eh.. its not bad.. its a great company, I've road in tune ESS tuned cars, and ESS supercharged cars, there great. I just think JB4 or the Procede is the way to go! My car on the highest map beat a stock sedan M3. Lol it doesnt get any better than that. Cost me 700$ installed.

Ya but the piggyback I can turn it off at anytime, I just hold my cruise control button down, and right back to stock. Great feature. Plus its good when you go to the dealer you can turn it right off.
