I Recieved My Nelson Tune For My 05 Rcsb 4.8l 5 Speed, Man Is It Awesome. It Feels Like It Has A Ton More Torque, And The Top End Is Incredible. I Would Recommend A Nelson Tune To Everyone, It Is Simply Amazing. Thanks Allen.

 

glad you like the tune, give it a few 100 miles and you will like even more.

 

Nelson Is The Man

 

Is there anyone that dosen't like Nelson's tune? LOL.

 

There are a few but you cant please everyone. Mine is awesome.

 

Hopefully I will get that tune someday!

Storked 4.8L do you mean 3:73's? or 3:83's in your mods list? 3:83's seems like an odd gear size!

 

another happy nelson tune owner

 

heres one!

 

whats the deal, why dont you like the nelson?

 

I am very pleased with my Nelson tune and I have about a half a dozen other guys in my area lined up to get a tune from Allen because of the gains I got from his tune. His customer service has always been excellent for me also!
