I noticed you mentioned Bren tuning. Were you planning on buying the hand held device and getting an unrestricted tune? There is an issue if you install the Bren tune and afterwards the dealer automatically loads an upgraded stock tune. This could happen during the break in service and subsequently unless you tell the dealer not to load any upgrades. It sounds like a potentially expensive hassle.
The unrestricted Penner tunes work great according to reports. If the stock bike isn’t hot enough for you, you can get ~170 rwhp at WOT with the unrestricted tuned. You have to get the Android version of Tuneecu and the necessary hardware (tablet, phone, Bluetooth module) to load it. It’s much cheaper than Bren. The potential problem is with the new bikes. Penner’s tunes are modifications of older stock tunes. You need a base tune compatible with your VIN. Stock tunes are now available from Tuneecu for Rockets with VINs from AV5457. You need to make sure that this stock tune is compatible with your 2023 model. If so, then you can copy Penner’s tables into the new stock tune and load it to your bike. Penner’s tunes were done for stock bikes. If you are planning to make significant modifications to the exhaust and/or intake, plan your tuning options accordingly.
