[QUOTE="96dreamer, post: 16662747, member: 52560"] I was still having issues with a lean spot in the lower part of the fuel map and issue with power falling off above ~6500rpm. Duty cycle of the 80lb injectors was up around 95% at 6500 rpm so I bought a set of Bosch 210lb injectors and height adapters and clips along with a set of adapters to go from ev6 to denso adapters. I liked this particular set of height adapters because they incorporated an inlet filter into them. Many of the cheaper ones don't. the hat is crooked in the picture because I was seeing how much the hat could tilt on the injector [ATTACH type="full" alt="20210714_141952.jpg"]1718769[/ATTACH] For whatever reason the injectors were about 1/8" taller than the sd 80s so I had to oval out the hole on the fuel rail slightly. [ATTACH type="full" alt="20210718_160657.jpg"]1718770[/ATTACH] At the same time I also added a radium engineering fuel pulse damper to the driver fuel rail. I am thinking that the random lean spots that I was unable to tune out were due to some fuel system harmonics with the new big injectors. I screwed it directly into the fuel rail adapter and 90'd right off of it. [ATTACH type="full"]1718773[/ATTACH] Lastly when I originally installed the ls2 d585 coils I made up stainless leads to the plug for the coil on plug setup. They worked nice and firmly clicked the coil to the injector. I problem with this setup however was that water would get into the plug holes and started corroding the plug end of the lead. There were also broken strands on the braded cable on every lead that wasn't originally there. I am not sure the ferrite donuts I put on were accomplishing anything at all either. [ATTACH type="full" alt="20210830_195924.jpg"]1718771[/ATTACH] To replace this I ordered a factory replacement set of Denso cop springs and boots. I crimped 8 new spark plug wire ends for the coils just large enough that I had to "thread" the spring onto the crimped end.
