Took the car out and did a little tuning today got the idle very close to where i want it and a quick fly by video. I need some damn traction! couldnt even get on it more than 21% according to HP Tuners before it started spinning lol

Were those fast fuel rails tough to modify and have you heard anything about the holley rails? Which injectors did you use? Are you planning some dyno pulls? very professional build man

I haven't heard anything about them I really like the fast rails but I actually had to go through two sets before i got the right ones. The set that fits on the ls6 intake are one number and The other ones that some people get are specific for FAST intakes only. I can give you the one for the LS6 intake if you would like or even take a picture of the fuel rail on the car.
I used the 80lb siemens injectors that are very common with these turbo builds. I have the FP at 58psi so they are actually 95.5's right now
I will do some dyno once i get the tune perfect just trying to get some nice pulls with it but weather stops me from doing that.............Thanks for the comments!

Nice work.Did you get the idle problems sorted out? I have the same injectors and can't get mine to idle better than 11.9 to 12.2. If so what did you do?

Yes i had some help from another member on here but it took me a good 6+ hours of adjusting to get them to idle where i wanted now idles 14.2-14.7 Still have some surging after beating on it but i'll take care of that next.
You gotta get the correct injector data first and there is a whole list of things to do after that. If you have the data for them start working on the ve to lean it out. Hp Tuners? Speed Density? A little info on what you have done would help.

Did you get the right injector data? What fuel pressure? I really don't know what you have adjusted. There's a bunch of things you need to adjust so it can even start going lean. Short pulse adder min pulse volts vs rpm etc ...

Ditched the rod ends and found these for 100 with the the adjustment tool.


It should be against the law to run rod ends with a spool it was so awful!!!!!!! Think ill get rid of the rod end on my torque arm next

a Anti roll bar would help the rod end noise greatly.

Yes it would help. I have all rod end suspension inthe rear and it was horrible until I added the ARB and that eliminated all of it.

Ya my exhaust set up last year was more obnoxious I had long tubes with a borla and the plates. It was basically open headers haha



But now its only loud if your on the passenger side. Its kind of funny from drivers or the rear you barely can hear it. Not used to that. Maybe a bullhorn would help lol
