Accelerator Pressure
Installed FiTech 30005 600hp system,no problems with install and made a big difference in the performance. Only problem is pushing the gas pedal requires a lot of pressure is their any easy fix?
I had the same problem with the 2 throttle body setup and I never got an answer from Fitech. I got so fed up this summer when engine refused to start hot. I had to have car flat bedded home. Next day started fine, but when hot refused to start again. I had the setup on for 2 years and never had hot start problems till this year. Getting back to the stiff throttle and the hot no start, I put the edelbrock carbs back on and it solved all my problems. Could never feather the throttle, almost like a brick holding it back. And of course with the Fitech help line I didn't want to spend a day on the phone on hold. Good luck with a solution from them. By the way mine is on a gen2 472 Hemi.
I always install a solid metal bushing in the big hole on the throttle linkage. This helps a lot. Also upgrading to a cable throttle makes throttle smoother. Some guys have unwound the linkage spring one turn and got the desired feel. I have not tried that.
Since I have a Mopar I use the edelbrock 1481 adapter to install the stock throttle stud on the throttle body. The car is stick so I don't have any transmission kickdown linkage to deal with.
Took your advice and installed bushing in upper linkage hole. Now it works like it should thanks for the tip
Called Fi Tech and they don't carry a bushing
