I've got the evo ti exhaust running on standard chip, second map with pipercross filter and it runs sweet. It seems to fuel much better than the standard can which had the baffles removed. It idles well and is crisp and responsive. I've heard people mention that the ti chip makes the bike run fairly rich?
Pm drrossi on here with the details of your bike, he'll sort you out one of his chips. They are brilliant, made my '01 rsvr feel like a different bike. Then get your CO levels checked/balanced by a mechanic who knows what he's doing, again this will make a huge difference.
There's loads of posts on here reviewing the drrossi chips
