Is a 10.9 a good run for an almost stock 04.5 cummins? The only thing done to it is a 5" exhaust. This was my first time ever down the track. I didnt know I was running the 1/4 so I let off and coasted the rest of the way right after the 1/8th, but the Chevy 1500 barely passed me at the end . Is this good?

 

probably about right. a lightly modified 12v will run it in around a 9.80
