I have a 2007 Ultra classic that has been punched out to 103. It has Zippers Stage 3 heads on it with Redshift 577 cams, Ness Big Sucker and D&D Fatcat 2 into 1, also a HPI 55 mm throttle body and SE 4.89 injectors. I just this past winter installed the D&D and the throttle body. I upgraded to the 792 map with the Thundermax hardware. I had issues with the IAC tuning and it was showing both cylinders running lean. Of course the fuel mileage was crappy and finally the Thundermax quit reading the rear cylinder altogether. I got a new O2 sensor thing that it was the problem but it made no difference. I ordered a new Thundermax and had Fuel Moto load a map into it. Now bike is hard to start. Any suggestions? Do you think if I go into my laptop and load the Thundermax 792 map it will make a difference?
