Moved here :D

I don't know the exact amount. But, the weight alone is going to hurt you :(

Thanks kat I didn't know where to really put it. I didn't know if anyone had ran both and figured up the difference. I didn't have time to go swap tires last night and I was turning 14.6's. I know I was losing rail pressure and had way to much defuel on the tune but that will be worked out pretty quick:D. I know the tires killed me, I just don't know how much was tires and how much was tuning. Otherwise I had the backseat, sparetire, tailgate,and one battery out so I was fairly light. It would just fall on its face when it would shift.:( but as soon as it would shift it would set you back in the seat and go till the next shift.

Well the weight of the tires probably killed all your other weight reduction :(

What where your 60ft times?

Thats a fairly slow time for an EFI tuned truck. What HP do you think the tune has?The tires would probably take 2/10th out of it from stock tires.

60' times were 1.9's I didn't get but two runs in and didn't have hardly any boost built up when I left. I know that is slow for an efi live tuned truck this is a new motor with supposedly 20 over injectors but they seem to be more like 40 or 50 over with an lbz pump. I am also running a 66mm turbo I should be close to the 12's with my mods. I was turning low 13's before the motor went. It pulls harder than it ever did on stock motor it just falls on its face so bad that it kills my times.

That is why they call them shake out runs... You will get it dialed in :D

Where were you racing? I'm hoping my engine will be going back together starting next week. Once I have it up and running, I'll be looking to get it to the track pretty soon.
