Twin Turbo '74 Duster
cool stuff.
How did it run on the boost? I dislike Fi because at the stock level your limited to Max. Fuel Volume/Delivery capability, if you start off with nothing all the necessary components cost alot...then cost alot more to upgrade, and can fail because they are electrical.
I like tuning with a screwdriver so,
I am going the simplier route and staying with a carb...
I dig your gumption though...lets see what its got!!
