2003 S Type R HELP!!! restricted performance light

I have a 2003 S Type R that has the restricted performance light on and it seems to "chug" when I hold it at 40-50 mph. Rpms will bounce a few hundred. I've replaced the fuel filter and MAF sensor. What else causes this? Any ideas would be helpful... trying to stay away from the dealership costs if I can. No fun driving this beauty with restricted performance.
Thanks

You are going to have to pull the codes on that.......if you don`t have a reader than you should consider going to the dealer.....driving it when restricted is not a good idea...

Probably best not to swap parts but instead read the codes. AutoZone likely free and consider getting your own cheap code reader e.g. elm327 ebay $20ish.
