Ok, I guess I need to re-phrase the question?
I'm trying to maximize the tuning of my 2013 Triumph Roadster. I drive exactly the same as I did before but it appears that RamAir, headers, and TOR's cost 10mpg! Does that sound reasonable to anybody? I installed PCV+AT to try to improve the mpg and it didn't do a thing. Nothing, and practically zero change in performance. So is there a chance that a dyno tune could bring it up, or is that all I can expect with those modifications? Who has the same mods and knows what their gas mileage is?
Thanks
