It was a happy dyno as already stated. Say I have 190whp on a typical dynojet, you will have 10-15% more drivetrain loss. That would mean about 20-28 less whp, also every engine is different you can't say your at a certain HP by what I dyno by. Your car is not mine. Yes, I ran a 15.3 with a 2.6 60'. So when I learn to drive the car can easily pull a 14.8. What have you ran?

None taken. Have you been to innovative?

Buy the ZZP catted downpipe, with an extra O2 bung and an O2 bung plug.

You may or may not throw a code with it. I did, but nothing a tune can't fix.

Also contact Terminator. He tunes cobalts and I think he is in Tampa.
