I have the DTT/WEGO IID from Daytona Twin Tec.
It`s a great tuner setup. My 07 FLHX has RHTD`s with the SE-A/C.
The bike runs very well and has no heat issues. I just ordered the Thundermax/Redshift 575S cams from Zippers....The new cams should eliminate the detonation too.[8D]
Cant wait to get them installed and let the DTT retune itand see how it runs....
I just installed the S.E.R.T. with SE-A/C and SE Touring Slip-On`s on my 08 FLHTCU.
It has made a noticeable change with performance and heat reduction, but the aftermarket ECM`s work the best. I know the 08 has different cams with a bigger throttle body bore, but the DTT/WEGO IID setup works better when compared between the two.
If you have an 07 go with an auto tune ECM and you`ll be very happy with it. It`s money well spent IMO. The big plus is you don`t need to spend money and time to have someone else tune your bike.

 

The nice thing is there's a ton of sharp guys (not me!)on this board you can toss questions at, I printed a lot of the threads and keep them in my T-Max manual for reference. Sort of like having an expanded HD service manual available! You'll be smiling soon!

 

One thing no one has mentioned is the T-Max switches out the narrow-band O2 sensors for wide band ones. Do some research on the i/net on thetheory of wide band sensors and you will see the advantages.
