Options for tuning

1998 z28, i would like a tuner that is capable of reading sensor data while the car is running and check codes. I would also like to be able to change some of the programing like removing the secondary air system and making performance enhancements. thanks

HP tuners? I've used it for 99+ models, but I'm sure thay make a version for 98. It has a scanner software included with the package.
