I went to Dobeck and am in the process of purchasing their TFI unit. I have an 05 stock Heritage. There are 2 units and one is for a high compression bike. Is a stock 88 high compression? I know this sounds a bit silly to you tech guys but...... Thanks Glider for the tips and you will probably be hearing from me when I get the unit. By the way their military discount is great!! Saved almost a hundred bucks.
