Seems like DFCO is not working even though I have it on. Starting to think maybe I have some wrong data in my injector tables.I am running Siemens 60's. Also have a slight surge at low rpms 1000-1300 and at 2-6% TPS. Here is a scan and copy of my tune if someone can help. Also my throttle body is mismachined. My TPS doesn't always go to 0 so just ignore the 1-2% you see. I have tried to adjust with no avail. Will be at 0-2% with the throttle closed.
Thanks

Anyone?
I guess your boosted. Adjust the settings in "enable MAP vs Baro".
When you let off the gas, your MAP is still high. It doesn't get to the 18 which may be a stock setting.
05 CTS-V l LS6 l Maggie l Magnaflow Cat-back l Meth l 439rwhp/414rwtq
I will try that and see if it helps. I am seeing 18" of vacuum the moment I close the throttle but I will give it a shot. Thank for the reply.
