Thanks, haven't been keeping up with this ECU project but it looks like its almost at the stage where it will be dyno run tested for plug and play use. As for the secondaries I had no idea people were experiencing loss of low end, although in my case havering not installed a TFI remapping, air box mod, and new headers eliminating the CAT (something I will not be doing), I find it hard to believe that removal of the secondary's with just a can change and lower heat range spark plugs will not improve my low end LOL. No I don't plan on gutting this bike like my 05, just help it breath and perform a little better then stock and as close to legal as possible and at very minimal extra cost. Beside you know the old engineers warning: " The more you overhaul new plumbing, the easier it is to stop up the drain"
