Just wanted to toss this on here quickly. I was having some issues with my new DW300 pump dropping pressure at about 5800 rpms. i emailed them and got a very quick response with several helpful suggestions on possible causes. i got it fixed and it now works great. their customer service is excellent IMO and i wouldnt hesitate to do business with them again. for DeatschWerks!

 

So what was the problem??

 

Voltage to the pump. Wired in a relay and it holds pressure just fine now.

 

Good to know!
