5) don't know how good the AFR CAI is try the stock on again?
6) port the MSD (remove flash neer the port exits)
Maybe a dynamic that I is unique to the combination and the altitude; because 50 HP gain from cam is NOT bad with stock heads, especially a cam that is WAY too big and way too much lift (head flatspot in flow).

I'll try the ported heads no matter what.
My TB does not close, this is one of the obvious stuff to check when you tune.
I did not check my CATS. Had a weird vibration noise yesterday, I may have an issue with a broken cat. Need to check.
Porting the msd is an option.
