I have had this set up since it came out. I like the simplicity of removal and the lack of connections/potential leak points it offers. That being said I have dealt with a leaking issue from the outlet wielded AN fitting on the rail. I even have a second one they sent me that leaks in the same place. Not as bad but still leaks. A little teflon tape has fixed it. I have seen recent posts about some problems with the injectors but have seen where they are going with a different supplier as of late. I am getting ready to pull my motor and plan on getting a magnifying glass and checking the ones that came with mine out. Lastly I have also added a rubber cushion between the rail and the hold down bracket that seems to add a good bit of extra force/ evens out the area holding down the rail. Hope this helps...despite all my issues, I still use it and will be swapping it onto the new motor I am getting ready to install next week. i have the 755's with a Z1 ecu tune. I plan on adding Nistune with this new motor so I can dial it in alot better than a base tune.
