That's what I was using. I had one that came faulty and it took 3 weeks to get a replacement. The new one seems to work fine though.

 

the problem i was having was with 550s and a aem ems i was maxed at 360 whp and 13psi. so i bought 750s and crank up the boost to 18psi but they maxed out right away so im going to try an aem fpr and bump the fuel pressure. has this happend to anyone????
