Meh

Easy to install. I havent noticed much out of it. One nice thing about it is that you can read error codes with it and clear them.

WOULD NOT PURCHASE AGAIN

Reviewed By Steven R (Oregon City, OR) Reviewed for a 2005 Chevy Impala —9/27/2013 5:50 AM

Way to many things to disconnect to be able to use this programmer. The one for my old car did not require that anything be disconnected except for the OnStar. Fairly expensive for what it actually does.
