Like everyone will say is you need a good fuel pump and a good tune.

Ill find the tune.. but i pulled out a good bit of timing haha..
he had to put a new fuel pump in it and a fuel filter, it was cutting out on the 150 shot.
retuned and upped the shot..
never logged it in the 250 tho.. just took a wild guess and richened it up.
its still running

Whats a good gear for this much spray on a 4.8?? Im use to running a 4.10 but wouldnt a higher gear like a 3:73 be better on a small motor and alot of juice?? Cuz im thinking about dropping a big shot on my 4.8 but i need a pos unit and gears first, what yal think??

I sprayed my 5.3 with 200+ dry with a bone stock everything and it held for a long time. All i did was spray it through the mass air to get the computer to add more fuel. I think i ran about 75 bottles through it before it said no more but it ran good for a long time. LS motors + spray = <3. Joey you know what im spraying at it now. Just have brandon tune it and it will fly but you still wont catch me.
