Hey guys, I have an 04 Z71 sportside reg cab. It has the 4.8L in it. When I take off from a dead stop and I mash it, the tires won't spin or even chirp on dry pavement. It hesitates, then starts to move. It's a sport side...so being really light in the back with a fiberglass box, I thought for sure that it should be able to burn some rubber off the line. Any others having this problem? Not sure if I should take it in to get it looked at. I just got a Magnaflow cat back system on it, sounds great now, but I can't even show off to my buddies when I take off... Can ya help?

 

The Z71's have a beefier frame - don't let the stepside fool you - it's still a very heavy truck. There's also a lot of torque management that is controlled by the PCM that kills low end torque. Add to that you probably still have the stock torque converter. Throw a 2600 stall converter in there and you'll go through tires pretty quickly.

 

Get a custom tune done. I got the extended cab z71 4x4 with the 5.3 and after I got my tune done it would roast the tires so easily. I actually took the truck back a week after I got it done and got him to put the tranny pressure back at stock settings cause I figured I would blow something up!!!

 

What size tires are you running?

 

gonna be hard with that torque management and them 4x4 tires....

 

Thanks for the tips guys...didn't take all that into consideration.

 

dude.. effing SUPERCHARGER... works every time... hey guys.. sorry for no posts in a while.. spurr of the moment deployments..

 

Where to? or is it an OPSEC thing? Where's SC_Chevy_Lover?

 

I think SC-chevy is taking some new schooling. He said he was changing jobs, so I assume that is it, just too busy.

 

Ah... Cross-Training. That lucky *****. This job (SF) sucks...
