Well i had my truck up too 110 the other day and it was still goin i want to tach it out somday to see where it shuts off at. Wat are everyone elses top speed?

 

they de-fuel around 115...........I proved it with mine

 

Are you wanting just the Cummins or diesel's in general?

 

had the third gen to 120.... im to scared to go fast in the 2nd gen

 

Depends on tire size and speedo adjustment. I think mine defuels about 110-115. I dont have the drag upgrade but I do have an ADD that is supposed to take it to 3200. According to boost gauge it doesnt last quite that long.

 

115 in my 02 and had plenty to go! I had 3.55, 35in tires and a 5 spd. In my 06, it tops out @ 95, that's red line!

 

i took mine to 102 going down hill before i did the gov springs. now it'll go faster i just have to baby it due to EGT's

 

I never speed...

 

had my 91 to 105 once, thanks to 3.07 rear gears and overdrive. Had more in her, but it started to get real floaty on I75
