Thats most likely your problem.

 

Take the super chip out. And put the stock airhat back on.

For real though. Unscrew your upstream O2 sensor and take a test drive. If its a lot more powerful your cat is clogged. Which means your plenum is probably bad

Either way, check your plenum. It's probably bad anyway. Do you get any pinging? Codes?

Also overdrive is for flat land, so that's not a problem, just the way it is

 

+2, the plenum is shot.

 

have noticed a little ping but seemed to stop with 91 oct. no codes

 

91 octane and no ping = blown plenum gasket. Seriously, read the plenum sticky. I know it's long, but you'll find out what you need to know.
