2007 S4R with full termi kit - horrid gas mileage - any advice?

Quick update



Well I emailed DNA and explained to them about the lack of support from the dealer here, I then went into the dealership and told the owner I'd contacted DNA and I wanted this bike fixed now.  This actually got them moving instead of just saying "hmmm, and the other bikes get better gas mileage. and they are the same year and everything, well I dunno." 

They've got the new ECU on the way and also new throttle bodies now.  Both of these will be replaced and the bike will be hooked up to their computer that checks out the bike.   Hopefully this sorts out the bugs with the bike.

That sounds encouraging. Outside of the T Bodies and ECU the only other thing I can think of is way high fuel pressure. Have em check the pressure/regulator too.

Good luck getting this fixed and keep us posted.

good thought on fuel pressure. make sure the fuel lines were not reversed at some point. You would have too high a pressure and run rich.
