Any experiences on a 440i xdrive? Using 93 octane as well. Was planning on Dinan Elite/stage 1 this summer.

Active 8 will provide a lot more power than Dinan

Yes, but what about safety in terms of impact to the engine or trany or other mechanics?

Every single tune on the market right now is super conservative especially considering there's a fuel cap which limits how much power can be produced on pump gas. It's completely safe. I've had my AA tune for a year now, driven hard every day (multiple WOT pulls to redline, aggressive downshifting/upshifting, etc), no issues at all. Dinan is just not worth it for the price. The company isn't what they used to be in the 90s.

Great feedback!! Thanks. What about errors? I've read some folks having issues, not specific to AA.

What kind of errors?

Most common issues when tuning the car are misfires caused by old spark plugs.
If your spark plugs are old, misfires will occur no matter which tune you use.

Active 8 is a very reliable tuning option

Trouble clearing CEL's... whatever that means. I'm newbie. I presume issues with clearing errors from various sensors (e.g. o2, etc).

Active 8 does not clear codes ... You need either a JB4 or a flash tune to clear codes.

So AA does trigger some error codes? I assume appear on instrument cluster?

AA does not trigger any codes but if you get codes from other mods, AA will not clear them either

Nope, no CEL unless you run a catless or even high flow catted dp.

From the moment you push that pedal down after install, you'll get a better idea of what the B58 is truly capable of.

No tune clears codes anymore, as JB4 is now CARB compliant, if I'm not mistaken.

Correct but I think you can still manually delete them on the jb4 as they appear so its no different than carrying around a $40 maxi scan tool around in the car. O2 codes will pop up every 30-40 miles or so.

do I need to upgrade the intake to maximize the tune?
