i just had the rsm kit installed on my car a few weeks ago and when i start the car the rpms shoot up from a thousand to over 1800 n then drop down to 500 of 600 hundred in just a few seconds..sometimes when i put it from park to reverse the it will stall beacuse the rpms r to low..any ideas what is wrong

I assume you have the proper tuning for boost? It sounds like you have a sensor problem, or the IAC motor is phucked. More likely, you've got problems with the MAF, IAT, or TPS sensor. I would scan and find out what those sensors are reading when you're having the problems.

If you can scan, try and find out what the IAC motor is doing when all this weird stuff is happening. Also, makes sure the TPS and MAF readings are steady, and that the IATs arn't all weird. If that stuff all checks out, maybe its a mechanical problem, vacumn leak, etc.
