Re: im curious again (as usual)
About the tbi, it gives you more horsepower and better gas mileage. The disadvantage is stock computer and wireing harness. your best bet is aftermarket that way you can adjust the computer settings to your likeing. I have a 4.3 with tbi and it has balls to the wall, my next step is a stage one hyper chip which should give a 10 to 15% increase in horsepower and torque.
