Sorry it has been so long but honda quit bringing dyno to bike night. now they have a wheelie gizmo. So untill i find some one in area with dyno. I do know that where it used to take me to 120-125 to catch GSX 750. I know pass them at 60 with D-Boost switch on. Stiil 120 or so with off. As far as running lean PC mapping is as close to tuned as possible. Now this is R-6 to a GSX 750. So after switch is fliped there is a diff some where. As far as fuel milage it is switched so not on at all times just when passed or at track.
If I put 4 of them on my bike, will it give me an extra 100 hp? :biggrin: Since my 1993 VFR doesn't have EFI where would I stick this chip?
basically fools your car into thinking its still cold, making it dump extra fuel. doesn't work, unless the motorcycle or car is tuned poorly enough (for fuel mileage/emissions) that is runs lean with the stock tuning
