Latecomer, sorry!
I'm with Hybrid, the only time I'd go with TBI, would be when I did my GQ Patrol, I put EA 3.9 injection on it, as it was quite easy, and very cheap, and all I really wanted was better cold start, and no fuel bowls for better wheeling ability.
But if your spending real money, why go backwards, or sideways. TBI is basicly just and electronic carby.
