TBI vs. Carb

The biggest downside to the stock TBI system is its not tunable at all. They were adequate for only stock engines and ran only marginally better (if at all) than any well tuned carburetor. They are not the same as the systems on the market today (sniper, fitech) as those are somewhat tunable. If you want fuel injection skip the middle ground and go multi port with a completely tunable stand alone (Holley hp, megasquirt, AEM Infinty, motec) You won’t be disappointed.
