*Stingy dyno and couldnt get the 4L60 to lock up.

GenIV 4.8 with cats deleted, air raid JR intake tube, Vinci Stage 3 low lift truck cam. I originally ran the cam with LS6 springs and 5800rpm shift points. Before the spray tune I moved up to BTR Platinum .660 duals, Titanium retainers and hardened pushrods. Factory 4l60 and stallm 4.56 gears and heavy offroad style wheels with 275/55r17 General UHPs.

The tune is with timing retarded for the 150 shot. She peaks at 6200NA and pulls until 6700 on the spray.

Is that the NA number or with the 150 jets?

 

thats with the bump, according to his post

 

So it makes 250rwhp with the mods off the bottle? I know it's a 4.8 but damn. Shoulda kept it stock
lol

 

4.8 with a cam 398whp? Of course it wasn't

 

It must be a complete slouch off the bottle.. Respectable numbers on the bottle. Now ditch the n20 for a turbo kit and make 500/500+ all the time

 

I knew it was on the bottle, it was more a joke that it would make around 250rwhp off the bottle.

 

decent tire on it. plus, unless he left it out of the post i’m under the impression it’s on stock manifolds and crap exhaust but I could be wrong.

 

I am not sure the impact tires have on dyno readings, but I made 477 with 12lbs (P1) and 302 N/A with 33s and 4.10s on a 5.3

 

I know all about rotating mass. The tire he runs isnt that heavy at all. My tires weigh 83lbs a tire without the rim.
