Thanks Rusty. When you read all the hype about fuel injection it sounds like the way to go. I wasn't a believer myself. I'd always believed that if you properly tuned a carb you'd be just as well off and save a lot of $$. But there were info sources around that claimed that there was no way a carbureted vehicle can perform as well. Theoretically the self tuning aspect will enable a car to run optimally throughout the entire RPM range while at best a carb (they say) can only be adjusted to a point where the air/fuel ratio will only be optimum in a narrower RPM range. I have to say, we did see a substantial increase in power after installing it. But, we had yet to get that 750 Holley dialed in before the swap.
