Pardon me if this has been previously addressed, I tried the search function and didn't find the results I'm looking for. I have a 2011 T800 with a SDP I picked up for farm use and want to get rid of the problematic DPF and EGR systems. Going to keep the twins, not looking for high HP, want reliability. Good tunes? Tunes to stay away from? What hard parts should be removed/replaced? Thanks.
