Ask them how much it would cost you to have them install it if you bought it yourself. Also make sure to specify it's JUST the PCM (assuming you're talking about your 05 on you sign) some of chysler's fine techs aren't always that attentive.
when i asked they were going to charge for injectors also. It's really not a hard install mopar provides very good instructions. However I understand if you don't wanna take the risk if you're not that familiar with engine electronics. But ask how much just the install is. I ordered my S1 from my local dealer and paid about 500 before I saw haynes had them for less. This is a worth while upgrade you'll notice the increase in power when you floor it.
