Sent my Igniter to Triumph Twin Power a month ago and I recieved it back about a week ago. I installed it the other day and finally got to take it out for a spin to see if there was any noticeable difference in performance. I had the rev limiter bumped up to 8500 rpm and ignition remapped to I believe 3 degrees. So I took her out and took it easy at first and then hit the open highway and cracked the throttle and wound the gears out but never hit the rev limiter (I really wasn't trying though). It definitely seems to pull harder and it actually feels like I have a 6th gear now. It definitely made a difference and I am very happy with the results!! I would recommend this upgrade. The only downfall is the downtime with shipment to the UK. From the time I shipped it out to return was almost 4 weeks. Luckily I shipped it out when it was too could for likings and still too much crap on the roads. RECOMMEND!!
