A/F/R gauge for tuning
I've run an AEM-0300 on my 1972 Scamp, with a LA360, for years now. I have found it invaluable. My Scamp runs about as close to feeling like it has fuel injection as a carb can run. And my WOT is tuned perfect.
I have all the dragstrip data from the previous owner. Between his best run, and my best run, through the use of the O2 sensor, I have increased the WOT power by 65 hp. Well, that and a whole new exhaust (the exhaust on the car when I got it, was rotted out).
