does this "sound" normal - TT Z06 rev?
well here goes:

it kinda sounds like the turbos are spooling more than they should at idle, rev. Out the tailpipes, I could hear a slight turbo whiste even at idle, might suggest that my AFR is off, however I have the regulator at 60 and the car is tuned to 14.7:1 at 58, doesnt sound like it would cause much of a difference to me.
Any other suggestions?
car is a 427 with baby netics T3/T4's 0.81 a/r, and the exhaust is a complete catless dual exhaust.

hows the oil feed to them? I thought it as a dam rearmount from how it sounded lol. I woud recheck the turbos and see if they are the right ones. That vette has a big rig turbo whine to it lol I want to say they may be too small but I dunno. Maby you just have a well built dam good flowing kit. Oh is that sound on a cold motor?

It does sound wicked and every single person on the road has to stare lol, but I just want to make sure there is nothing wrong. I will go over it again and check the AFR, a rich AFR/ or less timing can do the same thing, since it makes the exhaust pulses denser etc...
However you are right about the turbos being a little small for a 7liter engine, those turbos generate enoumous torque, but would max out on power below 6000RPMS on a motor made easily spin a tad above 7000RPMs.
ill check a few things today and see what i come up with.
