What do you guys think.
Full bolt on
vig 3600
3.73
224 112
2.5 5.3 heads
Seems a bit low to me, especially the torque. We are thinking the dyno reads a little low. My buddy with a afr/x4/90 setup only made 45x on the same dyno. Any input?

Yea i did some racing last night and beat a h/c lt1 6spd pretty bad from a dig.
Ive never seen a h/c ls1 a4 or m6 with that low of torque though, but it does run good and its safe now. Before it was WAY lean and pulling timing. I have a mail tune before.

My car makes great TQ and low HP, I just really have a hard time when it comes to trusting dynos on our Stalled Autos.
In my opinion, the dyno is great for tuning, you can see how each change can make a difference in power, but the REAL, HONEST story is told at the track by ET and trap speed.

The reason the torque looks so "low" is because the converter is locked.

I told john we can run em to see how the cars stack up to each other.

How do I go about advancing the timing? By the chain? Also, if I have the timing advanced would I have to get it retuned? Thanks guys.
