Not all dynos are created equal and it might be a bit conservative. Your trap speed seems to indicate you are right around 500. Do you have any scans from the run? Make sure your ecm isn't pulling any timing or throttle. Those LT motors can be a pain to tune if the torque tables are off.

I’m running TSP V3

Mine is a Pray cam that he customized for me but it is probably pretty close to the V3 cam in size. I wouldn't worry about getting to that as you sit if you ran 10.8 @ 126. Did you run that time before or after the MSD? That is the only thing you have i do not have yet.

Negative batman, Street/track tuning is by far better than a dyno tune. Dyno's are better for not having to go on the street making WOT pulls or having to wait on the track to open.

Where in South Texas are you in? Self tuned or someone is tuning on it? Like everyone else has mentioned don't get hung up on dyno numbers.

Port your intake and exhaust ports, that will get you there.

Cam too big for NA? CSP just pulled a big na cam out of an otherwise stock C5Z, and put in a much smaller cam. Pulled more power out of it with a more usable power curve.

I guess seeing all those cam cars running 530+hp got me thinking about my setup .
Hopefully I get a 10.6 today

I make 480 on the stock cam
Sounds like you need a better tuner. Hit me up if you want a reco.

Reco=Recommendation
My tuner specializes in the LT1 engine
Tunes/builds them all day and night
Went to a special school specifically for the new generation LT engines
