no pinch here.

 

I ran a 15.32 bone stock the week I bought it and haven't been back to the track since.....

My exhaust does have the pinch in it but mine is on the passenger side pipe where it goes over the tranny crossmember....I've thought about replacing it at times but with the twin-turbo plan I have I'm going to replace the whole exhuast anyhow so it can wait...

 

Bump for a old thread if anyone is still around lol

I still have my old truck. Runs 15.1@93.8 mph now.....still on 87 octane

 

Wish I had my 06 back. It ran a 10.13 bone stock open rear. Traded it because of gas mileage. Now my 14 gets the same with Whipple. Should've kept it.

 

"Should've kept it" I've read that so many times about the NBS trucks.

Never had mine to a track, and tried to get some sort of 1/4 time on the backroads a few times but no solid data. Must be somewhere around that 16 second mark, although I could probably get slightly better with a foot brake start.

The WOT 2nd to 1st downshift is pretty fun, but once it's back into 2nd around 50mph it's meh.

 

Not sure if anyone is still on here but I have a 2004 2500 crew cab, tvs1900, ls9 cam, 90mm throttle body, arh 1 7/8 headers, 4.56 gears , 3" dual exhaust with X pipe, yank pro truck converter, tuned by black bear performance. I'm thinking I would run low 13s.
