Something on my end must be acting up when I tried to send a message to hanso. I can't see where it went out. So I'll just post it here for him to see as well as all other captains out there. My Rocket is in the shop for it's 20,000 mile service and while there I'm having a PCIII installed(please don't beat me up about PCIII vs PCV, I'm going with the III and that is it) and a custom map done. With a PCIII will I need a O2 eliminator kit as well? After this is done should I still decide to can I upload the TORS/CAT delete tune from Tune ECU, or would that have to have been done prior to the custom PCIII map? The same question would apply for the tri-filter map hanso sent to me. With all the discussion I've had about air filters I'm thinking that with a stock head pipe there wouldn't be any noticable power gains from adding a tri-filter setup. However someone who I'm aquainted with told me his 05 standard with a stock headpipe, Maddog slip-ons, tall tri-filters with something like velocity stacks in them, and a custom tune using a PCIII yielded 146HP(don't remeber the torque number). To me that seems pretty impressive for a daily ridden R3. For now I'll just be happy with whatever comes out. With what I've added and weight I've taken away there has to be a decent bump in power with the custom PCIII tune. I'm trying real hard not continue to be the tweaker that is my nature(just ask my now ex-girlfriend about my $40,000.00 hotrod that until a couple years ago couldn't quit trying to squeeze more and more out of it).
