I have an 06 PSD 350. I have purchased the EGR delete kit and the oil cooler as well. Before I install them I was wondering the out comes in regards to performance from others after the delete. I hear of "limp" modes that the engine goes into and am not sure if a delete is the way to go. I am not interested in losing more power but MPG increase would be great.

 

you will get no incress in mpg or power. you will/ may have a reduction in boost levels... reduced boost is not always abad thing. the power level will be about the same.
you will have a check engine ligh t if you dont trun off the erg valve function in the pcm.
