Hello Everyone. Brand new to this Forum.

Just purchased a 03 Yukon Denali XL. Last Friday had the Magnacharger Radix S/C put on along with JBA headers. Dealer told me stock exhaust was fine.

Of course, I only did all of this so I could better pull my trailer...

Nonetheless, I don't have access to a dyno or dragstrip yet. Anyone care to venture what my HP, Torque, 1/4 mile, 0-60 would be? Additionally, any tricks to launching?

Thanks in Advance.

Low 14s/high 13s?

 

REALLY??? HOLY S%^T! Here's hoping!

What I had read on the web suggested perhaps around 1.5s off the 0-60, which stock was supposed to be around 8 seconds. So a 6.5s 0-60 run would have put me high 14's or so. But then I was confused by what I saw on the Lingenfelter website where their GM Suv's were running 0-60 in around 4.7s with around 700 hp or so (which mine is a couple of hundred hp short of).

At any rate, Thanks for your estimate.

14.6 - 14.8. The XL's are heavy rides. An intake and exhaust along with the headers will help the 6.0 breathe better.

 

Mid to high 14s

 

Any suggestions for the intake and exhaust? I was thinking about those as well.... Volant and Magnaflow perhaps?

And there seems to be a lot of posts on this site, from my searching, about Allen tuning being superior to the Superchips tuning which came with the kit. Would still be ok for towing?

Thanks

12.9 at 110

 

Damn dude HOW many ants bit you? Are you feeling ok? Fever?

 

I think nelson could do a better job than the superchips tuner. Go to his website. I think he advertises huge gains with radix/magna set up.
Mid 14's

 

yukon xl isnt that a suv. i would think if it were the suv then mid 15's. if its the truck mid to high 14's or a low 15.
