Just to revive this thread since I haven't been here in a while!! lance ran a 8.70 at the track in the 1/8 on 22's!! I sold y truck and bought a diesel and its tuned as well!!!! ha how you guys been doing?

 

HELLO GONZO!!!!!! Lmao!! Long time no.....well post! Ha how U liking the new 6.2??

 

Hey Bros! hows the cuznz?

Like many things about it some i dont ,tranny doesnt always know what gear to be in. 010 was better,lots of tranny gear noise low speed,engine has great power for stock,rides stiff because of the NHT,010 truck was soft like all others.It was you that went oil burner? whats up with that?

 

Haha we are doing good man!! Yeah lances truck rides stiff to me because of the 22's I thought. Because daddy has a 2014 ccsb 5.3 gmc and it has the 20's like yours and rides smoother....I needed more truck to do my hauling with and wanted something I wouldn't have to worry about when I tow something. Got tired of borrowing daddy's 2011 Duramax to haul the heavy loads! So I got a cheaper truck payment and more truck all in one!! My truck had 220k miles on it and it was 3.5 years old and I owed like 19 on it....well they paid it off! Ha and I got a good deal on this truck and extended 100k mile warranty! So now I got about 900ft lbs Trq instead of 375! Ha

 

Hey I thought there was a race vid ,you running him after he got tuned.Guess that never did happen?

 

In my 6.2 truck? Oh yeah it happened! Ha I have it on my other phone! I'll get it tho and post it!!
