Hello, I'm about as an inexperienced programmer as there is and have been fiddling with my tune that a shop did a few months back. I am running the ACDelco MAP Sensor 12615136 but the tuner did not install the speed density OS when he tuned the car. So I decided to go ahead and install the OS that showed available which was "Speed Density - 2 BAR OS 1250161". Immediately after upgrading on first start wideband showed car running lean. I used the instructions on this site to force the computer into speed density mode and was able to get the wideband reading back down and did some driving around to get a base. Since I am inexperienced and I was done playing for the day I reloaded the original tune back into the car.
Once again on first startup the car shows running lean and it does not appear to go into close loop any longer. I tried copying the main VE table from the speed density tune to the original tune but it does not appear that the changes made had any effect. Would appreciate any help available. This is my first post since purchasing the HPTuners package, I've attached both the speed density and original configs.
Thanks
