I initially purchase the TMax as my bike had excessive pinging with my basic mods\\; I figured it would also be a good long term investment in case I added more.
It has ran great with map #403, but the mileage has been gradually getting worse, and when I last checked my spark plugs, they were a little darker than expected, but still within normal range.

With the degrading mileage concern, I decided to reinstall the stock ECU and sensors for&nbsp\\; a few weeks to see how they are doing.&nbsp\\; To my surprise, I believe my bike is now running better than it was with the TMax. I also noted that the wide band O2 sensors were fouled black when I removed them\\; possibly the source of the problem, but was the TMax contributing to that condition?

 

My mileage is back up and I feel the bike is running stronger\\; primarily down low.&nbsp\\; My only question now is do I need the stage I download (engine safety) or should I just wait a bit longer and go with dyno tuning?

 

Go to Latus Motors and see if they have a SERT MAP for your combo.
If they do you probably can do everything yourself and save $$ on a dyno tune.
