Here the TWM site:
Borla-TWM Induction - V8 Kits (423) 979-4045
and the FAST site:
Fuel Air Spark Technology - Leader In Electronic Fuel Injection
these two kits work very well together. It was simple to install and dial in (this took two people and a spirited drive). My dyno sheet is in my pics. The feeling in the car is strong, and forceful. I have a KC 427 and get around 20 mpg, but my right foot is pretty heavy, I could get better but that is not why I have this car!
