I have a couple coworkers who have been asking about my truck lately.They love the way the longtubes sound with the slp loudmouth. They both have 2008 trucks, one a GMC the other a Chevy. Both crewcabs on 20s with the same motors and the same options.The guy with the chevy says his cuts off at 96 and the GMC guy says his cuts off at 91. Both are pretty aggrevated at this so I clued them into getting a custom tune. They were both very interested in what all could be done so they probably will get their trucks tuned soon. I just don't know why there is such a difference in the speed between the gmc and the chevy. My 04 cut off at 100 stock, well according to the speedo anyway. Thanks for reading my long drawn out book.That is all.

 

mine cuts out at 99 as per the speedometer

 

There are a few Sponsors to your right.....

 

Yes, I am aware of the sponsors. I did point them in the direction of my tuner who is also a sponsor here.

 

Mine without tuning also cut off just a tick over 90. At least that what the speedometer shows. 130 seemed more suitable to me. haha
