Thanks everyone!
It's on its 2nd build, but that's mainly due to forcing OD 4th to 160 at WOT awhile back on the first build hehe. It bled out at the pump seal.
The Boss was at 408 rwhp for this vid from before. Just want to be fair to a badass Boss, and young driver:
So to answer some of the questions for those interested...The GP is on the same setup as before, ~10.5psi. The Boss has some bolt-ons, put down 408 untuned shortly after that day run.
Differences between earlier video (chronologically) and now:
And yes it's so cool daily driving this car like a grandpa out of the boost 98% of the time on commutes knowing the cutouts can be opened up and violence unleashed at any time

Differences between earlier video (chronologically) and now:
- back then the GP had Walmart windshield washer fluid in the ww fluid tank ( ). This time around, 50/50 water/meth which is what it is tuned on.
- Fuel was cleaned up a bit in the tune recently.
- Colder weather, mid 40's in the latest round.
- Trans temp was high in the GP on the day run after just running a 480rwhp C5 right before.
- Boss had his girlfriend in the pass. seat on the high rolls.
- 40-roll favored the Boss, higher rolls are where the GP likes it.
- First run (posted) the GP got a nice brake-boost.
- Oh, and the Boss fixed some trans issues it was experiencing around the time of the day run.
And yes it's so cool daily driving this car like a grandpa out of the boost 98% of the time on commutes knowing the cutouts can be opened up and violence unleashed at any time

To be fair, if that black 5.Br0 didn't have a passenger and the driver wasn't 350lbs I think it would have been a tie. lol
More good runs though!
