When I installed my Jars, I had the Triumph dealership install the TORs tune. It was never right and I didn't realize how wrong it was until I switched to TORs yesterday. It runs much better but upon startup, seems to trying to "find itself". With the Jars it started right up and settled in. It surged at idle though and had a lot of decel back popping, running very lean at low throttle openings.
The difference is significant at low RPMs now with the TORs. At idle it is very steady but it does meander around for about 15 seconds at startup. I am now wondering if the ECU somewhat set itself for the Jars and if the 12 minute tune would resolve the issue. Other than that, I love the TORs. I'm sure I also would have been very impressed with the performance of the Jars but just never got used to the exhaust note and never got around to installing the PC3 in order to have the correct tune. The PC3 will be going up on the classified section shortly. It still sits on my work bench.
