Is it possible to tune out the bad drivability with lager cam? And how?
I have been putting up with this bucking and jerking (Trailer hitching) since I installed the cam.
I use Tuner pro with Quarterhorse Chip
Specifically cruising under 2500 rpm
Car bucks and jerks under 2500 rpm but gets better over that rpm.
Other than that car runs very strong...
92 LX mustang 347 cid 373 gears 5 speed
Comp Cams extreme energy 282 1.6 rocker ratio
I did degree my cam per the cam card.
TFS heads 10.1 CPR
LT Headers
#30 injectors
80 MM prom maf
Thank you for any help ... MB

Re: Larger cam good drivability
My guess is you need to work on dashpot preposition and decay rate in those areas or possibly reduce timing in those areas or both

Re: Larger cam good drivability
So basically, start by reducing dash pot by %20 at a time see if any change in drivability.
I data logged dash pot and it at %99 at that rpm while cruising, I'm sure that's to keep it from stalling when shifting or coming to a stop...
Thanks for your input.
