Also, I think I have read that the CAN tool will not erase a limp mode error. Is that true? If so, isnt this a red flag for the dealer, given how wildly popular the JBD is and will continue to be?

I have also red that the little white connector piece we remove before install is brittle and likely will break after a few install/uninstalls. Are these parts that your company can acquire and provide for sale?

Obviously my concerns center around my warranty.....esp considering I plan on getting it extended to 100k. Thanks in advance.
I leave the little white plastic piece out when going back to stock. Never had an issue.

The CAN tool erases everything as far as I can tell. Lately, I've just left it plugged in so when the car randomly goes into limp mode, I can press the reset button and get back to full power within 30 seconds.

Or, you could just turn the car off and back on, takes 5 seconds (yes, while you're driving).

I threw an engine malfunction code and the dealer didn't call me. But maybe my dealer sucks.

The car won't transmit codes. The CT can erase any hidden tuner codes. The little white piece can be thrown in the trash if you prefer, it isn't needed for the OEM connector to seat. BMS does not carry them.

I've done this tons of times in my N54 and now twice in my 335d. No problem. Throw the cat in neutral obviously.

I bumped it up to 70-75 today. Almost feels like my old SRT8 now.
Only i'm still getting around 29-30mpg with a lead foot.

I plugged in the JBD today and when I started it, the car just started sputtering, and the interior lights would flicker, as well as the crank is much longer now. Then when I removed the JBD and plugged in the OEM, the car is showing a reduced engine power code, at idle it's rocking side to side even though the plugs are back in tight, and the crank is still longer than normal.

Anyone ever had this problem before?

Really sounds more like an electrical issue.
All the jbd does is simply alter the fuel pressure. Shouldn't cause lights to flicker.

You need to disconnect and reconnect connector and check all other connections and clear all codes. Even if there is no Check engine light, you will have pending codes or BMW specific codes. After clearing it, lock the car and try to start it after 10 minutes.
