2011+ Challenger 6.4L Hemi Stage-2 NA Package Adds 50whp! 

I'm pleased with the work, National Speed hooked up my ride...thanks to the management team and most important the mechanics. I'll be back for Stage 3 cam.

Maximum horsepower point was gained simply by adjusting the SRV actuation up to somewhere between 4900 and 5100 rpm.

Oh I love it. Everybody else here on yt are ripping stock exhaust system off making it absolutely unbearable, at least listening to the video with headphones. You did what I sought for such a long time, LT or ST with stock everything + cats. It does sounds betterer and yet doesn't piss off neigbours, cops and officials. By the way, how are the stock cats holding up with added power? Do they last less or would a larger/longer universal cat be vise to install regarding emissions?

These numbers are kinda high they baseline lower than this. What dyno are you guys using ?

Hell yea currently own a 6speed 6.4 liter

Cat's out of the bag, the stock catback is the best aftermarket system..

I dont get the part when he said PCM unlock when your getting a tune. Why you have to take it out?

I have a 15 chal scat, be on the look out for me. My goal is stage 3 but i think im gonna start with stage 2. I live in Snow Hill, about 1.5 hrs from the Wilmington national speed!

What camshaft do y’all think would be best for a intake and header only scatpack?

What’s the SAE numbers witch is the true number

3 year olds know the number 30 and the number 50 aren't the same!

You would think The work that was done to this car in the video it should already be pushing 500 horsepower

All that for just barely 500hp mmm bet it’s like close to 10k labor and parts mmm nah I’ll keep it 485 hp not really worth it imo.

id be more pleased if i could get a response...
