I have a 2005 FLHTC with BB, CV40 and Yost Kit, SE flat tops, SE Performance Heads, TC1 cams, VAnce and Hines 2 into 1 Pro Pipe and Big Sucker air cleaner. It has the stock ignition. I had it dynoed and was not really thrilled with the results. Nice curves, the AFR was a little lean, 95 Torque and 79.5 HP. CV had a 190 main and 48 low but I changed out the main to a 195 today and it seemed to help. My AFR can more than likely be tuned up a bit by dropping the clip on the needle one notch. My question after all that is: How much would a good selectable or programmable ignition help out? This build should realistically have had a few more foot lbs. of torque and about 10 more HP based on basically the same or similar builds. I have only had one performance ignition in my life and that was a Crane HI 4. I never did get anything much from it but that may have been from my lack of knowledge and no dyno to help out. Thank you for any input.
