From under the hood-
The TPI seems louder on the new engine. The sound of air rushing into the 48mm throttle body is really loud- in fact, it nearly drowns out the side pipes.

DarkShark,
Looks and sounds great! 
Gives us some of the details when you get a chance. I can only guess that you installed the computer to run it, but how hard was to install, for the 1980's models did not come with a computer, unless it was a California car?

The TPI was really straight forward. My '80 is a 49 state car and did not have an ECM.
Here are some details- - Routed the harness through the HVAC grommet on the firewall
- Using a '7730 91 style computer and the ECM sits below the radio
- '81-82 Vette large cap distributor
- Early Iron head TPI intake (1985 Vette)
- SLP runners
- Lokar TH 350 cable
- Hybrid '80 Vette + '89 Camaro TPI throttle cable
- '89 Camaro plenum, 5.7 fuel rail

Sweet set-up. Did you upgrade to a 4 speed (or 5 speed manual) tranny?
