I have a 2007 FLHTCU that has no modifications and runs very hot. Iv'e been told the HD has a ECM download that would richen the fuel mixture a causing the system to run smoother and cooler. Recomendations have been: 1. spend the $200.00 on a stage 1 download then $180.00 for stage 1 intake. 2. spend the money on $460.00 and 2 hrs install and dyno and $180.00 for stage1 intake or 3. Purchase the Fuelmoto Vision and air intake upgrade that would cost about $320.00 Any thoughts on this? Thanks in advance.
