Ladies and gents,
I have had more than a few calls about Touring model performance. This should help out more than a few of you.
The Touring models are the same except for the exhaust and ECU calibration. BOTH are very restricted.The ECU controls the secondary throttles and actually closes them at higher rpm and higher gears. In the exhaust, the header is the same, but the box after the header is very restrictive. Slip-ons (TORS and D&D) really don't do much except for sound.
Neither do air filters under the seat. Triple K&N RU-2780 filters make a bit more from 4000-5500 rpm, but have the same peak power output as the stock air filter. The stock intake plenum and ducting actually makes more torque under 3000 rpm than triple RU-2780 filters under the bearclaw. It is not until you go to a full exhaust system that the RU-2780 filters make a difference.
A stock R3T or one with a slip-on exhaust tends to make ~86 hp on my dyno (~ 13% lower than a Dynojet), and 130-131 ft-lb of torque. Simply re-calibrating the ECU (mapping) tends to result in 115-117 hp, and 140-142 ft-lb of torque. A very nice improvement.
Attached is a "tune" for stock and slip-on exhaust R3T models, as well as a graph of output differences. Dashed lines are torque. Red is an R3T with TORS and stock air filter. Yellow is after tuning. This resulted in 43+ mpg cruising at 70 mph on 87 octane fuel. Speedo corrected for stock tire. Speed limiter raised. Ignition timing improved in lower gears. ENJOY!
You can also find this map on Tom Hamburg's TuneECU.com site under the custom Triumph tunes section. I have this tune downloaded but not on compatible format.
