I just wanted some opinions on using DSM 440's for fuel upgrade on a b series. I personally feel that using DSM's are pretty much a huge mistake, due to the fact that they randomly lock up when maxed out... i've seen them to be the downfall of 5 motors... to DSM injectors in my book.

 

i used them for a year. I wouldnt have one bad thing to say about them....

 

glad someone has something positive to say.
