Taken the thundermax off my 1200 converted iron and putting on a Dynojet power vision, I'm no mechanic or Harley expert, and I don't pretend to be, but I'll try to give you guys an honest comparison if you are interested when I pick it up after its been on the Dyno. 

 Forgot to mention also getting rid of the short shots and putting original headers with a set of S&S slipons.

get fuelmoto to send you a base map for your setup, to save dyno time.

 Nah, was owed a bit of Dyno time, big difference, a lot more roll on power, better down low, and fuel economy, fuck fuel economy!! Wish I got rid of those short shots earlier, sounds heaps better, I'll wait to see how the power vision goes in different weather and temps, but so far I like it better than the Tmax auto tune. Looks like I'll be selling off all the old goodies, short shots, tmax, fuelpak, hyper charger.

Where in Brisbane are you and who did you get to dyno it?

I'm in Bris with a Nightster and a powervision but I have a 2 into 1 system... wouldnt mind comparing some time?

 I live on the south side, I'll pm you the details of the place I go,

 I have a power vision and got Fred at Procycle Dyno in Springwood to do the tuning etc

I recommend him to anyone. 

 after i get my rebuild done ,we should all hook up for a ride some where iam on the gc 

you've got 800k of sub 90kmh to go before you can really enjoy your new engine parts.

 Rode mine hard straight off the Dyno,
