I forgot to post but I went to the track two weeks ago and ran a 15.71@88mph.

Had a 2.5 60 foot.

Also spun a little off the line....

Thats with 20's,trac and stabilitrac off. Manual shifted and stalled it up to about 1200.

Only mod is a muffler.

 

glad you posted this. Been wanting to know about what my truck should run. this is the same truck i have, a 11 ecsb 5.3. Mine is completely stock but i have 17" rims

 

Should run better than mine then!
