Default EFi LS24X Connection Swap Complete :) Dyno Results in, Video added

Me and my buddy just installed the Efi kit took us about 2 days to complete it, I only took a few photos off the finish product. The instal went smoothly and didnt run into any trouble, the car fired right up and no codes were thrown. Fired it up and drove it straight down to get tuned so hopefully i will have it back in a week and let yall know the results

**UPDATE** I attached the old dyno sheets. And the New dyno sheet is on pdf file I attached it as well. Can't figure out how to get it to paint yet, Dont have the nitrous dyno i will get it though
I just got the car back and dyno
Motor
Last Dyno with Opti- 393Rwhp 382Rwtq

I do not know yet, took us a day to do the harness and a day to install it, I fired it up and just drove it straight down to get it tuned so I wont know if it helped me or not im hoping so. but far as driving it down the highway it felt fine, didnt wanna get into it with a stock ls1 pcm tune

That makes sense. I was just curious. From what I have read it is a great mod to do.

LT4 make sure you change the injector bank select in your tune or your fueling will be off. If you need help with it let me know

from Efi i bought the 24xlt1 conversion package for single row timing set includes in that kit.
*24xcrank reluctor,24x crank sensor,cam sensor, cam sensor housing,1x cam reluctor, DIY harness= $580 bucks.

The rest of the stuff i got mostly on here
