its probably the 87 tune

[casey23]

its probably the 87 tune

I agree..... 3.73 with 33" tires .... that isnt helping anything !!!!! and 87 tune i bet is pretty weak...

sounds like you need a stall for sure!!

[bluecajun5.3]

something ain't right and even on 87 it should still be faster. it might be pulling timing down low because of the summer heat.
my Z in sig still has the 5.3, 3.73's, 33's. only mods done is 87 tune, cai, magnaflow, and efans.

so im guessing i should get some street tires to run on at the track. but is there anyway i can get my tune to run on 87oct and then when i go to the track put 93oct in it. And the reason i dont have a stall is because i tow every now and agin but didnt know if i could get a small stall and still be able to tow

[oleshifty]

a tb verter will be a slight stall...still allow towing, prolly your best bet.


And ya...I'm pretty sure I run faster then a 15.9 and I'm on 36's

My Z71 ran a 16.0 bone stock. It is a RCSB, but regardless... you should have picked up much more than that.

[CHEVROLADE]

u need gears,or run stock wheels

[silverado120]

isnt there two different kind of tb verters like 2100 and 2500 or something like that.which one should i go with and how much time should i pick up with that and stock tires. the powerband for my cam is 1200 to 6200 rpm. i just wish my truck would bogg down then go off the line
