those are good numbers! im glad youve had good luck with dps parts! maybe he's changed and makes good parts now? cant wait for the numbers with higher boost
We've always made good parts. The problems arise when people order parts without telling us the entire application and expect them to work wonders. ie, putting Stage 1 sticks in a N/A engine and expecting no smoke, putting injectors in an engine with a wiped out pump and expecting it to "fix" a problem, putting a turbo pump on a N/A engine and expecting miracles, putting injectors in on a improperly timed engine without re-timing and expecting them to fix a problem, etc. etc. I could go on.
Another wrench that gets thrown in is when, if someone has a problem, whether legitimate or otherwise, tearing the injectors apart and sending them to the local diesel shop to get "fixed" instead of sending them back here for warranty or calling us to try and figure out what's going on. Of course anyone with a pop-tester is going to squawk about what the spray pattern of our injectors looks like, but it is working for the designed use - getting more fuel out quicker. I'm not going to argue the physics/theories as to why these things work great in a pre-combustion, turbocharged engine as we have over 275 sets of these on the market and I can count the number of people that have gotten back a hold of us with actual problems with the injectors on one hand (the number is 5 BTW). Out of those 5, 1 was a wrong app (smoked too much on a n/a engine). Problem fixed by swapping out a set of stock reman injectors. The other 4 were failures (cup cracked, threads stripped while installing, spring broke (2) and they were all handled by warranting out the units.
I'm not here to argue with anyone or bash any products. It seems that a lot of the "problems" we're hearing about is someone's neighbor's cousin's roommate's friend had an issue. Our biggest issue we had was when idi injector sales started to really take off, we would run out of cores on a regular basis and that would slow down shipping. We give customers 2 weeks to send their cores back to us, and that bit us in the butt. Orders would back up and we would be running around trying to find injectors. This is a non-issue anymore as we have found a source for almost unlimited cores if the need arises. If you actually have a problem with product that we sold, call the shop. You can't expect to get anything taken care of if you don't call us.
The shop is growing at an exponential rate right now and we may not be able to get to the phone on every call, but leave a message and someone WILL get back to you. We're still working on getting a hot secretary, but they are hard to come by

That said a friend of mine can easily and fairly quickly hit 15psi with his 088 and that's with only an open element cone filter and a 4" exhaust.
