Just got my SE4 in black and silver last week with reinhart TD, SE breather and SERT (All done before I left the dealer).

They didn't change the A/C, said I don't need to change it. It runs good for a tight engeen (300 miles) except with occasional back fire (mild). But I did noticed that going up the ramp in a parking lot, it didn't have the tQ that my old 05 FLHRCI has. Talked to service manager and he said they will re-tune it at first service. Upper rpm is great, going 80 m/h at 3000 rpm. The bike runs a lot better if I keep the rpm over 2000.
I love the sound and the look of RTD.
What I don't understand that what map they put on it? HD has no maps for RTD or 2008 bikes for that matter. and I know the dealer is not buying maps.
By the way, HD has lost it's contract with SERT software company and once they sell what they have, they would need another softeware.
The good news is the SERT developer is going to market a new version for HD with a lot of new options (I hope an upload option from bikes module) and they will offer firmware upgrade for older SERTs, but we have to send the module back to them for upgrade.
