Diesel Care and Performance injector rebuild kits

[S_L_W]

As the title implies, I am looking at these injector rebuild kits and was just wondering if anyone has any experience with this company and/or these nozzle kits? My injectors are ok, however I do think I have a few bad o-rings, as I get a small couple puffs of blue smoke when first started in the morning, along with ****ty MPGS(about 12). Not that injector o-rings are the cause of my low mileage. Anyway, any thoughts on these? I figured these with a good custom chip will help in the power department quite a bit.

I installed these in my truck last week..... found the kit on eBay then called and talked to them and ended up ordering over the fun.... I have an E99 and tried ordering the 99.5 and up ones but they told me they would sell them to me but not warranty them..... but other than that..... they are pretty quality and looked great (I replaced all 8). Each Kit (one kit does one bank) came with 4 rebuilt injectors with brand new o-rings installed, new valve cover gasket with brand new wiring harnesses pre-installed, and 4 brand new glow plugs.... I've only put about 120 miles on the new injectors, but all seems to be well.... my buddy got permission from his boss to let me do them at his shop and now after seeing the kits, they are gonna start ordering all their injectors from Diesel Care is that says anything (they do a lot of 7.3 diesel stuff)... That's my $.02
