Well put this chip in my maro 2day, what a difference well worth the money in my opinion, gotta find out if it gets rid of the speed limiter but increased power was a deffinete. However at one time, my idle out of gear was around 2000rpm, I pressed on gas real quick twice and it dropped to like 500-1000rpm where I like it. Anybody know why it was idleing at that rpm for a time? Thanks in advance.

 

The ECM will need to relearn all its job after the chip is changed. Driving the car around town for like 15 minutes should do it. As for the rpms, maybe your TPS snd IAC need to be cleaned and adjusted.
