i plugged the scan tool into my truck today and it has 229200 miles and codes p1209 and p1212 which are both for icp it said but im not exactly sure what is causing it

 

A gajillion things can cause an ICP error, including a hot tune. Scan tool (what kind?) or code reader?

 

i used a snapon scan tool and do you know like a couple of main things that could cause those code and I do have a dp tuner on it but I have been running it on stock and it did turn a check engine light or service light on

 

Yeah... I have a couple of ideas. That SES may just be an overboost (DP doesn't hide those from the PCM). As for the ICP, can you log your data on a WOT run?
