to make sure this is clear to all, this is only after the ISO update with a catless DP?

Before, with the 'regular' JB4 and catless DP, it has worked fine?

When I experienced my rough idle which eventually leading to the car jerking at a stop sign and stalling out, I had jb4 iso, catless dp, bms intake, and chargepipe. took off the jb4 and gave it to the dealer. they replaced a fuel pressure sensor and my oxygen sensors on dp. I did not experience this before ISO.

In my case....I'm a YES. Prior to the ISO update everything was perfectly fine!

If anyone is still having a problem with this, I suggest you try what Mike suggested...My car stalled on me 4 times and idle was all over the place this morning. I went home and tried what Mike suggested about switching the MAF sensor back to stock and my idle went completely back to normal, no rough idle, no stalling, after driving about 50 miles.

I was having similar issues and had a bank 1 sensor 1 fault code. I fixed the O2 sensors but the problem only got worse. My car has now been stalling at lights, its always stuttering and also misfires. I'm having multiple misfire codes as well. Has anyone had this issue? I was told it might be the injectors but I'm not sure. Do you guys think putting the MAF sensors back to normal or updating the DME will fix the problem?

I did this....It made no difference for my car.

Do catless or don't do it at all....Catted DP's aren't worth the money vs. power.

Just got my dp installed this last weekend. I seem to be the total opposite. My idle was bad when I switched to ISO and it would stall sometimes at lights until the car was warmed up.. My idle seems much better now that I installed the dp and switched to map2.... Wtf? I mean, I'm not complaining..

Soooo I'm running JB4 ISO right now without a DP, but my 4" AA one is coming in on Saturday. I don't know of anyone else on here running the AA DP + JB4 ISO so we'll see what happens
