Triumph 675 tuneecu custom map

This 675 came in from another local workshop to help them diagnose a running fault causing a big lack of power above 10krpm.
It was found to be down on power & running very rich so I suspected a blocked cat in the exhaust system.
The exhaust was removed & the cat taken out witch was found to be damaged,the exhaust was welded back up & a full system map loaded in the ecu using tuneecu software & things like the exhaust valve & lambda sensor was deleted out the ecu & custom tuned on the dyno to get some absolutely amazing results.
Plus 30bhp peak power increase & 40bhp increase at 12k so the customer will notice a massive difference in power the next time he takes it out on track.
