I dont drive often, and when i do it only gets in boost at the track

 

Yea I must put at least 200 miles on my truck a week when I'm not working on it. And I romp on it quite a bit. Mines not a race truck yet

 

I still have the tune on the rich side and am working out some of the little issues I'm seeing. Here is a 65-115mph pull on 15-16 lbs of boost at 17* of timing. IAT's went from 70 degrees to 88 degrees during the pull and I'm spraying meth after the IAT. Check out how hard the speedo is still pulling at 110+mph. Makes me think what it would run at the track at this level.

 

Yeaaa Buddy!!! I don't think you are going to be able to break that 4.8L

 

Don't try and challenge me. Haha I'll be putting the radials on this week sometime and running 20psi through it. We'll see what happens. It was getting kind of scary last night downshifting into second at 16psi. It would walk for a sec and then grab hard. I think I have a vid of it spinning through second gear up to about 80mph

 

How is first gear with those radials? Still worthless?

 

They dead hook from a launch on the street but I haven't tried downshifting into first at like a 35 mph roll. Not sure if they would hold then or not. Really glad I went with 15's though.

 

What PSI do you run them on the street? Dead hooking on the street is VERY impressive.

 

I think they were around 22psi when I was testing them out. I did a few 6psi launches and they spun only spun once but I stayed in the throttle and they grabbed and went. So I thought it must have just been some loose gravel I was on off the line.

I don't have the cubes you guys do so tq off the line isn't great. I need a converter change and/or trans brake

 

I run mine at 35 psi on the street and they'll spin, but not nearly as early as the street tires were. Tire pressure is critical for the drag radials. I drove mine home 35 miles from the track on 15 psi and they were solid as a rock.
