Had my cousin do a before and after test with a Nelson tune, cousins truck is a
11" silverado z71 5.3 ext cab
Took it bone stock ran a
16.1@84
Went a did a quick 93 oct Nelson tune with Allen and straight to the track today and got a best of
15.3@90
Pretty good gain my cuz was happy with the improvement
Btw that was without a wideband hookup.
So thanks Allen for hookin up my cuz .

 

Fkn a! run with the besf and leave behind the rest!

 

damn. nice gains

 

We're going to do cold air pulley headers ten re tune and going for 14s

 

With that I see no problem getting 14's. Amazing what a tune does on these new trucks!

 

yea the damm truck scratches up to 3rd gear lol

 

Allen is definitely no slouch in tuning

so you ran it bone stock hauled *** to nelsons had him tune it ran back to the track ?

if different days, how close was the weather?

 

Ran the truck stock on a Wednesday got it tuned Saturday then ran it Sunday weather was about the same low 50s

 

nice results! stupid new trucks are just as fast as the older SS trucks lol.
