trouble code p0275
First of all, sorry I haven't been around lately. I just got back from an 8 day florida trip and christmas and everything else was real busy. Ok now down to business. My SES light comes on occassionally and I scanned my historical codes and it came up code 275 which is boost control failure (overboost). Does anyone have anymore information on this code? I cant even find anything on it in alldata at my dads shop. Also, I did replace my boost control solenoid recently so that must not be the problem but I do have a smaller supercharger pulley. Could the small supercharger pulley be causing it? I am having such bad luck with my SES light recently and bad gas mileage. Any help would be tremendous. thanks

The PCM overboost protection COULD be setting a history code with a smaller pulley. Do you feel or see your boost drop off on the high end with WOT?
If you're getting overboost, try the re-plumb of the solonoid. A couple posts in forced induction regarding that.
