Went to the dyno after the bigger injector install ( 72# @ 58 psi) and efi live auto tuning.Made 619 rwhp and 657 ftlb. I'm really happy with the combo now cause we left the dyno hamering on it and a few bursts up to 120. Absolutely no kr and 11.5 afr. It RIPS
Auto tuning was done on the street before going to the dyno.
Boost was peak 15 # dropping to 13.5 got to check to see why that is.

 

wow, nice #s!

 

That peaking and leaking sounds familure, let me know if you find a solution. Sounds like a great tune, did you upgrade any other part of your fuel system? Do the injectors feal lazy (throttle response)? Is there a noticable difference between the old injectors (what was your old injectors) and the 72's? In the future I plan on upgrading as well. What is your compression? Nice #'s

 

nice numbers, how about a chart or vid?

 

I also recently put daul intank 255's in. Great throttle response, old injectors were 57# siemens...biggest difference old ones were at 111 % duty cycle these are at 79% lol. Compresion is 8.5 /1 Thanks

 

Thanks, maybe i can get dyno sheet up tommorrow... I was supposed to bring my camera to get MJHoward's truck on video but we were scrambling with some last minute stuff and i forgot the damn thing . His truck is really sharp and put down some good numbers to boot ..and there is definatly more in his setup.

 

OK, my daughter helped

 

killer curt!
One day my 6.0 may will live up to the 5.3

 

great work there!

 

Very impressive numbers.
