Made a little video this morning. Wanted to see how bad the vibration was on my truck at 100+ and to get a top end video. The only vibrations I noticed on my truck was right around 110-114. After that the truck smoothed out. Truck seemed to pull well up till 120 and then the last 10mph was the struggle.

 

I still wouldn't risk it at that speed on a stock driveshaft. You may not feel the vibration but I bet that driveshaft is doing something crazy when it's far above it's critical speed.

 

how is that tuning wit klug?

 

Looks real good to me.

That thing really 0-70s pretty dam good

 

Wow, it flat out hauls the mail for a tune only 5.3.

 

Very happy with it. He has been tuning for 10 years now and knows how to get all the power he can tuning wise out of GM motors.

 

Yeah after seeing some pictures of what can happen that will probably be one of my only top end runs. Trapping at 97mph in the 1/4 so I'm safe for now till I get a few more mods lol.

 

I can't find a site to look at his stuff.

 

Search for Klug Performance on Google and it should have a link to his Facebook page.

 

looks like it runs good

but you are on borrowed time w/ top end runs & stock driveshaft, as already mentioned


i have started researching new shafts for my ride, few good choices out there.
