Yes selliott it is stock tune. Here's where we are at now. I took it back to the garage on Monday. They left it running in front of the shop and it stalled twice. Each time they checked for codes but there weren't any. They don't know what the problem is. They were going to get a Mass Air Flow Sensor and a ECM from a wrecker and try those so I brought it home to await the parts. The next morning it would not start at all. Parts finally came in 3 days later and they came and towed my car to the garage. Tried the MAF sensor - no change. Put the ECM in and had it reprogrammed - still won't start.
