2.4 cobalt motor tuning

Got a really high idle now. Can swap ecu's to a tuned one and the issues go away. I know I need to tune the ecu but im still learning maps and graphs and how to read them properly. I have a race next weekend and need a good tune. It a 2.4 out of a solstice with a standalone harness in a cobalt. It just has a ported throttle body and big runner intake. Everything else is stock. I don't have the time to mail in the ecu and get it back in time so I need to buy the tune and have it emailed to me. If some one can help me out I'd really appreciate it.

Read your ECM and read the tuned one and copy the differences over. Unless the tuned one is tuner locked.

After that, tuning isn't really a buy a tune and load it.

Hornet class? I have good tune but it?s from a cavalier pcm cable throttle pcm. Ours was cammed as well though
