So I bought a used 2008 that has the Uptite pipe on it.
It's lean as hell I believe, bucks pretty badly and randomly on constant throttle at cruise. Has a very abrupt forward lunge on throttle transitions. Doesn't like to start if stalled when hot unless I set the fast idle lever first. Generally nasty to hold smooth throttle at the bottom of 1st gear trying to just put along on a trail.
I don't think it's had any mods done other than the slip-on. Sooo..
What have you guys done with the Uptite pipe (mine is spark arrestor type)?
I know about the 'powerup' resistor for race mapping, so that's on my list.
I know about removing and plugging the O2 sensor too.
Have you guys removed the CAT too?
Have you guys then remapped or will the race map mod balance out if I remove the CAT and open the intake filter?
I don't have any local dyno shop that I'm aware of, so a custom remap with the iBeat here in NJ is highly unlikely.
I'm not looking for racing performance honestly, but I want smooth throttle response and I do actually like the higher mileage and I know motors will run cooler when they aren't leaned out to death.
Any help appreciated.
