Why don't you time the DP change and ECU tune at same time. Step 1: buy a DP and have it shipped. Step 2: Ship ECU to tuner so that when it comes back tuned, your DP has been installed and waiting on ECU. I personally wouldn't mess with doing one before the other but I have another vehicle too. I just would want to avoid the hassle.

On your second question, I drove with stock SCR for about 6000 miles after tune and DP install. I might have gotten lucky though. I wouldn't wait that long. A portion of that 6000 miles was with urea still being injected which likely messed up my SCR that much more since it was mixed with soot.

Just like Cuda said, its best to do both at once, however, if we are talking about a week of driving, it should not effect anything. Also, if you come down for a dyno tune vs getting a mail order tune, I always recommend to have the car with all mods on to optimize the car to its full potential. You can ask sleeper, we did around 15 pulls to knock out his tune, of course he had a lot more mods than an average 335d

I was going to call you but got busy.
So if I at least do my downpipe then get the tune, then I got alittle time do do the scr?
I have meth @ 800ml single nozzle and the forge motorsort boost coupling. And should I take off the bms juice box too?

If you do the downpipe & tune first, I can do a stage II tune, it only smokes a bit on take off and will not cause issues with the SCR filter. Once you delete the filter, you can come down or mail me the DDE and I'll update the tune to the stage II+ for the cost of shipping or if we do it at the shop, I'll re-dyno tune the car for $100.

As for the JBD, i've heard mix results, you can test it out and see how it reacts with the tune. I'll be free in the am tomorrow if you want to talk (10ish)

My experience told me in 250 miles with a tune, the dpf will generate over 30psi of differential pressure at 50% throttle at 2k rpm.

As others have said, the scr seems to last about 6-8k after a tune.

thanks fella's just trying to get this done around my scedule. And scar someone's ass on the streets all at the same time.
