Finally got this done.... I should have the dyno graphs up here sometime next week. I swapped my AP2 intake cam for an AP1, changed the drive by wire manifold to AP1 manifold, and new throttle body. When we started tuning it we ran into a problem with the coils, so we switched to coils off an LS1 engine.... which worked like a charm.

Pre: around 420whp, can't recall the torque, but the torque did not hold very well at all the the AP2 cam. When we look up the dyno graph from the last tune and post it, I'll have exact numbers.

Post: 511.7whp, 341 ft/lbs torque.... and now it holds the torque at the top end.

Hope that's helpful..... like I said, I should have the graphs up soon.

 

did you up the boost as well?

 

Nope... actually lowered it from 18 to 17

 

Thats pretty incredible. Just intake cam? why not both?

 

From what I read, the AP2 exhaust cam gets the turbo to spool quicker than than the AP1.

 

could you tell me more about your manifold swap? did you convert to throttle cable? what else(aside rom the manifold) was needed to swap everything if you did?

 

Yes, I was already converted to cable before I did the manifold swap. I went with a 72mm throttle body. I had the side opening, where I believe the maf sensor sits, welded shut because I was using a different maf sensor. And I had to swap the coolant temp gauge.... that's it. The bolt pattern is different on the AP1 manifold vs the drive by wire, so you do have to change out the throttle body.
