Alrighty
So I have a bdl TB for my car and the throttle spring was way too strong for my tastes. I gave them a call and stock its a double wind set up I had them do a single wind and it is much easier to modulate..A touch stiffer than stock and the initial travel (just off closed throttle) is a bit hard but much better than the double wind IMO..

If anyone has any other techniques for throttle sensitivity chime in..

I wonder if a rising rate spring may help...

 

mine is stiff also...I wonder how i can correct it but i cant order a different spring since i dont live there..

 

I bought a Skunk2 70mm and its like stock!

dont know why BDL is like that!
