My friend has a big block chevell that ran a Kinser toilet running on alcohol , 14 :1 compression .The car ran 8.70 at 150+ mph. So, he decides to buy the FITech 1200 HP set up. He don't know squat about electronic stuff but he installed it. Surprising to me now the car starts right up, idles like a stock engine, still radical but has instant throttle response and still running alcohol. The FITech did slow the car down .3 He says it is because the FITech doesn't flow as much as CFM as the toilet did. Now I must say this car repeats every run down to the thousants, 60 ft. , 1/8 and 1/4 mile. He's even going rounds . Whats with that? I should have bought the FITech instead of the Holley dominator. I can see one in my future.
