Nelson Tune 6.0L 1500HD

[ChevelleSS]

I went to San Antonio and had Allen tune my 2003 1500HD 6.0L Crew Cab. The only other mod I have is a UPD air intake. G-Tech time before was a 16.31 quarter mile @88.50mph and the temperature was around 45 F. I finally ran my truck today after the tune and it done a 15.75 @ 94.6mph and the temp was 63 F. The increase in time was .56 in the quarter and it should run a littler faster at the 45 F temperature as my base run. Hopefully it will get a littler cooler soon so I can have a better comparison but I wanted to report the improvements I have gotten so far. Thanks Allen.

I'm keeping this post at the top for a long time, lol jk.

That's great , I'm glad it made such a nice improvement for your truck. Also, if i remember correctly that was on the cheap gas right, hahah.?

If it was, let's do the 93 tune someday and knock a few more tenths off your time.

thanks for the post and it's always an honor when you guys drive so far for a tune.


thanks,

allen
