mine does it without the shift kit and with the 22" wheels on, with some cheap factory tires is really breaks them loose

 

i can get a 2nd bark with no shift kit and a hypertech 87 tune. i would hope a shift kit and 93 tune can get em to scratch.

hey jow, when are yall plannin your trip? what part of texas are you in?

 

It's a 2001 excab 4.8 with a 160 thermo, K&N FIPK 77 series, descreened MAF and a 40 series delta flow muffler. And now I just put the Nelson tune on. I'm going to put true duals in a few weeks when i get some cash. Are high flowing cats worth it.

 

Do you suggest I should go down there too? I think I might go like June 6th or sometime around there. Also, what is the 02 bung or whatever that they can drill on your truck.

 

no i changed my mined and am going to run no cats for now. TX i am around the san angelo, midland odessa area. nightmare is getting his new tranny in and both of us are putting in the longtubes and delete the cats and then we are going on a road trip.

 

A i dont have a clue. but i hope i can get some more out of the truck with the LT's and new tune

 

Tranny should be shipped today and I have limited time to get it back to him so I may be going 2-3 weekends from now. Hopefully I can wake it up a little more by doing a little tune up while the truck is here in the garage for the headers/tranny install.
