Anyone running the Holley TBI unit???
Summit list it as a direct replacement, supposedly there is an increase in torque, and horsepower over the stock unit...Anyone know the difference between the two???Thanks, Tom

I seen that it says larger throttle bores. Something you can do to your existing tbi unit. Other than that it comes with new tps sensor and injectors. I believe the injectors are same as factory, seeing it is a "factory direct replacement".

Re: Anyone running the Holley TBI unit???
Thanks for the info guys....I am in need of a new tbi unit, and was thinking of that one, but if there is no improvement in performance, I will pass on it......I am not really very up on TBI, even tho I have had my car for years, and done some of the free mods.....Tom
