I'd say Holly. Not that anybody that's looking for a self-tuning TBI system wants to use a laptop, but it's nice to know that you could with Holley, even the Sniper. Usually it's only for touching up the idle if you have a radical cam or open exhaust or controlling when the Learn feature activates, but at least you can do it. Many low-end TBI system vendors just don't give us users enough credit.
