Also, you said you are in need of a tune in your sig...so you might just want to have the tune done on it. Might pick up some power from a retune.

But to my first point, if this thing hasn't been tuned since the cams, lay off it because you're probably going pretty lean up top.

Retarding the cams would result in a lose in JUST the midrange, right? Or would it affect the top end also?
If they weren't both the same it could cause on bank to have lower compression,hurting the power the whole powerband. A compression check will tell you pretty fast.
My tuner called a few weeks ago telling me about a Procharged Mach he was tuning that was about 100 rwhp shy of expectations. I suggested a bank to bank compression check since the motor had been assembled by the owner. Found one intake cam had slipped a couple of teeth during assembly. Lucky it didn't have any PTV. After degreeing the cams they picked up the lost 100rwhp.
